The house at 1531 Tyus Carrollton Road in Georgia sat quiet in the early hours of February 20th, 2025.
A stillness hung over the property — the kind that feels heavy, like it’s waiting for someone to notice it.
Inside, a six‑year‑old girl moved down the hallway of her home.
She pushed open the door to her parents’ bedroom.
What she found there would set off a murder investigation that would stretch on for months.
Her mother, Kristin Brock, 41, was motionless.
Her stepfather, James “Jamie” Brock, 45, lay beside her.
Both had been shot.
Both were gone.
She tried to wake them.
But they wouldn’t respond.
The child left the room and went to her teenage half‑sister —
sixteen‑year‑old Sarah Grace Patrick —
and told her what she had seen.
Sarah called 911.
Deputies arrived around 7:30 that morning, their vehicles lining the gravel drive, blue lights flickering across the windows as they entered the home. Inside the bedroom, they found Kristin and Jamie Brock, deceased from gunshot wounds.
A family shattered.
A crime with no clear suspect.
And a community left with questions.
In the days and weeks that followed, Sarah became the public face of the family’s grief.
She spoke about her mother and stepfather.
She posted about their deaths.
She asked others to keep their case alive.
At the time, she was a grieving daughter.
But nearly five months later, the investigation would take an extraordinary turn.
Sarah Grace Patrick — the teenager who made the 911 call —
would be arrested and accused of murdering her mother and stepfather.
And that leaves us with the question investigators, the community, and the family have all wrestled with:
What are we missing?
---
WHO WAS KRISTIN ASHLEY NOLAN BROCK?
Before Kristin Brock became a name in a homicide investigation — before her death became evidence, exhibits, and courtroom arguments — she was a woman with a life.
Kristin Ashley Nolan Brock was born in April 1983 and grew up in Rome, Georgia.
Her childhood was shaped by divorce and remarriage, and she grew up within a blended family of stepsiblings and half‑siblings.
Those who knew her described a woman with charisma and an upbeat spirit — someone who made people feel welcome, someone who loved deeply, someone who tried to build a life for her children.
Kristin became a mother to two children, Sarah Grace and Donnie.
And eventually, she married their father, Doniel “DJ” Patrick.
KRISTIN AND DONIEL
Kristin and Doniel were married for roughly ten years.
Together, they built a family and raised their two children.
But by 2018, their marriage was coming to an end.
Doniel filed for divorce — and what might have been a private separation soon became a complicated legal battle over custody.
According to court documents described in subsequent reporting, Doniel sought joint legal custody and primary physical custody. He also asked that Kristin’s visitation be supervised until she could demonstrate sobriety.
His filings included allegations of substance abuse and concerns about the children’s exposure to drugs.
Those allegations are important to understand.
But they were allegations — claims made during a contentious custody dispute, not established facts.
The July 2018 divorce order ultimately awarded Kristin primary physical custody, while the parents shared joint legal custody. Doniel received parenting time on alternating weekends and holidays.
For a time, that was the arrangement.
But the conflict wasn’t over.
A CHILD CAUGHT BETWEEN TWO HOUSEHOLDS
In 2019, Doniel sought emergency changes to the custody arrangement.
Court filings described new allegations concerning Kristin, James Brock, and the environment in which the children were living. Doniel alleged that methamphetamine and marijuana were being used around the children.
These were allegations made during custody proceedings — not criminal convictions, not proven facts.
But they added another layer to an already strained family dynamic.
And something else was becoming clear.
Sarah was no longer just a child being discussed in a custody dispute.
She was becoming old enough to have a voice.
According to reporting based on the court records, Sarah expressed a desire to live with her father and described feeling unsafe.
The custody arrangements shifted more than once.
A March 2020 order reportedly established equal custody and required Kristin to ensure Sarah received counseling.
By October of that year, Sarah was reportedly permitted to stay with Doniel during the week and return to her mother on weekends.
For a child, that meant moving between two households, two parents, and two very different versions of the same conflict.
And whatever the truth was behind each allegation, the court record makes one thing unmistakably clear:
This was not a simple divorce.
It was a prolonged, deeply complicated family dispute — one in which Sarah’s wishes and well‑being eventually became part of the legal proceedings.
And years later, that history would become impossible to separate from the questions surrounding her mother’s death.
---
As Kristin’s marriage to Doniel was coming apart, another man entered her life.
His name was James Matthew Brock.
James was born in 1979, four years before Kristin.
At some point after her separation from Doniel, he became part of her world — and eventually, part of her children’s lives.
By the time the custody disputes were unfolding in 2019, James was already Kristin’s partner.
That detail matters.
James didn’t appear in Kristin’s life shortly before the murders.
He had been part of the family for years — during a period when tensions between Kristin and Doniel were already playing out in court.
And Kristin and James were not starting with a blank slate.
Kristin had Sarah Grace and Donnie.
James had children from a previous relationship.
Together, they were building a blended family.
Eventually, Kristin and James would have a daughter together.
They weren’t simply beginning a relationship.
They were creating a household around children who came from different chapters of their lives.
For a time, life appeared to be moving forward.
But the relationship between Kristin and James would eventually become the subject of its own court proceedings.
JAMES BROCK
To the people who knew him, James — often called Jamie — wasn’t simply Kristin’s husband.
He was a father, a stepfather, a friend, and someone who became deeply involved in the life of his local church.
People described him as having a big personality.
He was funny.
He liked to joke.
Members of Catalyst Church remembered him as “comical” — someone who could make people laugh even on difficult days.
But there was another part of James’s life that wasn’t visible from the outside.
His heart was failing.
James suffered from serious cardiac problems and eventually relied on an LVAD — a left ventricular assist device — to keep blood circulating through his body.
It wasn’t a device he could leave at home.
It was helping keep him alive.
According to reporting about the family, James had undergone multiple medical procedures and was waiting for a heart transplant.
His health became a defining part of daily life.
Hospital stays.
Medical procedures.
The constant awareness that his heart could no longer do its job on its own.
For Kristin, it meant caring not only for their household and children, but also for a husband whose health had become increasingly fragile.
And yet, during those difficult years, the family found something that became central to their lives.
Faith.
FINDING CATALYST
Kristin and James became involved with Catalyst Church in Carrollton.
By the time they joined, the church wasn’t simply somewhere they attended on Sunday mornings.
They became involved.
They volunteered.
They helped with activities and became part of the congregation’s day‑to‑day life.
Pastor Ben Bonner later said the family “jumped right in.”
They weren’t people who slipped into the back row and left when the service ended.
They became part of the church family.
According to church members, Kristin, James, Sarah, and other relatives participated in multiple church teams and helped during the week as well as on Sundays.
Over time, Catalyst became more than a place to worship.
It became a community.
A place where people knew them.
A place where people saw them laugh, volunteer, struggle, and celebrate.
For James, that community also saw the man behind the medical equipment.
They knew the jokes.
They knew the laugh.
They knew the father and husband.
And they knew his heart was failing.
At his funeral, Sarah spoke directly about the man she knew.
She thanked James for the life lessons he taught her and described him as the best, honest dad she knew.
And when she spoke about his heart, she offered a reflection that carried its own weight:
She believed his heart was finally healed.
For a man who had spent so much of his life fighting to keep his heart beating, those words meant more than anyone outside the family could fully understand.
But the picture of Kristin and James’s family life wasn’t entirely simple.
Their relationship had also been marked by conflict.
There had been accusations.
There had been a protective order.
And there had been a period when it appeared the marriage might be ending for good.
Those details would later become part of the public record.
And they take us to 2022.
#A TROUBLED CHAPTER
In August 2022, the relationship between Kristin and James entered a very different chapter.
According to a family‑violence warrant, Kristin was accused of driving a vehicle toward James while he stood near a barn on their property.
A child was reportedly inside the vehicle, while another child witnessed what happened.
Kristin was charged with criminal damage to property in the first degree and two counts of cruelty to children in the third degree.
James then sought an emergency protective order.
The court granted the request, temporarily requiring Kristin to stay away from James and the children.
James was awarded temporary custody of their young daughter, and Kristin was ordered to leave the family residence.
In the protective‑order proceedings, James made additional allegations — claims of physical abuse, threats, property damage, harassment, and interference with a 911 call.
Those were allegations made by James during the proceedings.
They are part of the documented history of the relationship, but they should not be treated as established facts.
Then, only weeks later, something changed.
James asked the court to dismiss the protective order.
The relationship that had appeared to be breaking apart was not necessarily over.
In September 2022, Kristin publicly indicated that she and James were no longer together.
But the separation did not last.
Eventually, Kristin and James found their way back to one another.
And in December 2023, they were married.
Whatever had happened between the protective order and their remarriage, they were beginning another chapter — a family, a home, a life that, from the outside, appeared to be moving forward.
Until February 20, 2025.
The morning when everything changed.
Less than fourteen months after their marriage, Kristin and James would both be dead.
Shot inside their bedroom.
In the home they shared with their children.
And that history — the custody battles, the allegations, the protective order, the separation, and the reconciliation — is impossible to ignore when trying to understand what happened next.
THE INVESTIGATION BEGINS
With Kristin and James dead inside their home, investigators had to begin with the most immediate question:
Who had been inside the house?
There were no clear signs of forced entry.
Authorities noted that one of the doors was ajar, but nothing indicated that someone had broken their way in.
And then there was the weapon.
Kristin and James had been killed with a firearm — but no gun was found inside the home.
That left investigators with another critical question:
Where was the gun?
Without a weapon, detectives had to reconstruct the events inside the house using what remained:
the physical evidence, the layout of the rooms, the timeline of the morning, and the statements of the people who lived there.
They needed to determine who had access to the property.
Who had the opportunity.
Who might have possessed a firearm.
And whether any gun connected to the Brock household could be tied to the killings.
The answers would not come easily.
The scene offered no immediate suspect.
No clear narrative.
No simple explanation.
And as investigators began sorting through the evidence, the case started to shift — not because of what they found inside the bedroom, but because of what they believed had been happening in the months leading up to that morning.
THE SEARCH FOR THE KILLER
In the months that followed, investigators continued searching for whoever had killed Kristin and James.
The case remained unsolved.
Their loved ones eventually offered a $5,000 reward for information that could lead to an arrest.
Meanwhile, Sarah Grace Patrick was publicly mourning the loss of her mother and stepfather.
She turned to social media to pay tribute to them and ask for support.
And it was there — in the digital footprint she left behind — that investigators would eventually find another part of the story.
THE POSTS AFTER THE MURDERS
In the days after the killings, Sarah Grace Patrick began posting about the loss of her mother and stepfather on TikTok.
In one video, she talked about the emptiness of the house — how, at night, she would think about how much she needed them.
She captioned another post:
“Please send prayers for healing.”
But according to reporting from 11Alive, she ended that video with a line that caught attention:
“I should prob delete later.”
To people watching from the outside, these appeared to be the posts of a grieving teenager trying to process an unimaginable loss.
But investigators would later examine more than just what Patrick shared publicly.
Before her arrest, Patrick allegedly reached out to creators who made true‑crime content — seemingly trying to bring more attention to the deaths of her mother and stepfather.
According to People, a TikTok creator who runs the account Allegedly Reportedly said someone using the name Sarah Grace contacted her and encouraged her to look into the case.
The account allegedly suggested that covering the murders could be a:
“really big hit.”
She wasn’t the only creator who reported being contacted.
Another TikTok user, known as shoelover99, said someone identifying herself as Sarah Grace also reached out.
Her alleged message was strikingly personal:
“Momma tot I need a momma bad [right now] im going through it.”
On their own, none of these posts or alleged messages establish what happened inside the Brock home.
But investigators were no longer looking only at the crime scene.
They were beginning to look at Sarah herself — her actions, her words, and the way she behaved in the days and months surrounding her parents’ deaths.
And eventually, some of those digital footprints would become part of the narrative prosecutors would present about what happened that morning.
## SARAH AT THE FUNERAL
Then, in March 2025, Sarah Grace Patrick stood before a church filled with people who had come to say goodbye to Kristin and James.
At Catalyst Church in Carrollton, Sarah delivered the eulogy for her mother and stepfather.
She spoke directly about the loss — about saying goodbye when she had never expected to have to, and about being accustomed to having her parents there.
She appeared emotional as she spoke, wiping her face and at times struggling to get through her words.
But the funeral would later take on a different significance.
Some members of the Brock family questioned the sincerity of Sarah's grief.
James's niece, Krysten Dowda, later said she believed Sarah had been pretending to cry during the service. Dowda's interpretation was her own, and it became one of several things relatives would point to after Sarah's arrest.
The funeral footage would also be revisited alongside Sarah's social-media activity in the weeks and months after the killings.
What looked, at the time, like the public grieving of a teenage daughter would later be viewed through an entirely different lens.
But there was still a crucial distinction:
**None of those moments, by themselves, explained what happened inside the Brock home.**
The question was no longer simply how Sarah appeared to be grieving.
Investigators needed to determine what the evidence could actually establish.
And over the months that followed, that investigation would increasingly turn toward Sarah Grace Patrick herself.
## WHAT DID SARAH HEAR?
There was another part of Sarah's account that investigators would have to consider:
**What did she hear that night?**
James Brock lived with an LVAD — a device that helped keep his heart pumping.
According to a statement Sarah later gave to someone who spoke publicly about the case, she heard the machine's alarm going off during the night.
But she said she did not recognize it as something unusual.
She reportedly said the alarm blended into the background noise of the house, and that she heard it roughly ten to twenty minutes before she went to bed.
What Sarah said she **didn't** hear was even more significant.
She maintained that she did not hear the gunshots that killed her mother and stepfather.
That became an important question surrounding her account of the night.
If the gunshots were fired inside the home, how could Sarah have slept through them?
And if James's LVAD alarm was loud enough for her to hear, why didn't she hear the sounds associated with what had happened in the bedroom?
Those questions became part of the larger effort to reconstruct the night.
But there was a complication.
At the time, the public did not have access to the full forensic evidence — including the complete crime-scene findings, the precise acoustics of the house, or all of the information investigators had gathered about the timeline.
So whether Sarah's account was consistent with the physical evidence remained a question that could not be fully answered from the information available publicly.
And that distinction matters.
Because Sarah's statement was one thing.
**What investigators could actually prove was another.**
## FIVE MONTHS LATER
For nearly five months, the murders of Kristin and James Brock remained unsolved.
Then, on July 8, 2025, everything changed.
Sarah Grace Patrick — who was 17 at the time — turned herself in at the Carroll County Jail after a warrant was issued for her arrest.
She was charged as an adult in connection with the deaths of her mother and stepfather.
At the time, authorities said investigators had uncovered what they described as **“mountains of evidence.”**
But they did not publicly lay out what that evidence was.
What was known was that investigators had spent months examining the case, including Patrick's digital footprint. Authorities had not recovered a firearm at the crime scene, and the weapon allegedly used in the killings had not been publicly recovered.
Patrick pleaded not guilty.
She was later indicted on eight counts: two counts each of malice murder, felony murder, aggravated assault, and possession of a firearm during the commission of a felony.
She remained in the Carroll County Jail as the case moved toward trial.
But the trial would not happen quickly.
## WHAT WE STILL DON'T KNOW
The arrest answered one question:
**Who was the state accusing of killing Kristin and James?**
But it did not answer all the questions surrounding the case.
Authorities had described extensive physical and digital evidence.
The public, however, still had not seen the complete evidentiary picture.
The alleged murder weapon had not been recovered.
The prosecution had not publicly laid out every piece of evidence it says connects Patrick to the killings.
And as the case moved toward trial, the defense began challenging aspects of the investigation, including forensic evidence, chain-of-custody issues, records, and the testing of another firearm.
In July 2026, Patrick's defense asked for additional time to investigate those issues. Prosecutors disputed some of the defense's characterization, including concerns surrounding the additional firearm, saying that weapon was not connected to the murders.
Then, on August 3, 2026, the trial was postponed again before jury proceedings began.
So, at this point in the story, there is an important line between what has been **alleged**, what authorities have **said exists**, and what has actually been **made public**.
The jury has not heard the full case.
And until that happens, some of the most important questions remain unanswered.
