Luis wouldn't help out with step kids and was too jealous.
On October 13, 2013, Yessenia went on a work trip with co worker Kevin Dreden.
Luis sends her a series of texts accusing her of cheating.
October 16 she returns home wants a divorce.
He says ok.
October 22, he supposedly found proof of affair.
He went to her work and confronts her and Kevin.
1 pm, police are called to her office.
Luis slaps her in the face.
Later they meet at Yessenia's mom home.
Yessenia goes back home at 7:45 pm.
The next day, Yesenia doesn't call her mom, and her mom calls her and there is no answer.
She calls the police.
When the police get there, Luis says Yessenia left.
The police open the door to the house.
They were overpowered by the smell of Cleaner.
Blood spots in the bathroom and master bedroom.
The grandma calls the school.
The kids are not there.
An investigator talks to Luis, who is in jail from her assault.
He says they aren't missing.
He admits to the fight at the office.
He says she beats him and he never touched her.
Night before she disappeared he says she agreed to end the affair.
Just after 1 a.m. he goes out to his car, saw the neighbor Tyshawn and fell asleep.
He said he awoke 8 am. and the house was empty.
He says maybe she with Kevin.
Kevin was home with his wife.
Tyshawn approached police and tells them that at 6:18 am says Luis knocked on his window.
And he needed to move her car to a neighboring county.
Luis wiped down the car.
On the way, they stopped at some dumpsters.
He gets rid of some cleaning products and a trunk mat.

Luis said it was impossible, that he didn't have anything to do with his wife or kids disappearance.
Police believe Tyshawn, he took them to Yessenia car and to the dumpsters.
In the dumpsters they find the cleaning supplies, along with a vacuum, the kids stuffed animals and one of Luis' boots.
Everything had traces of blood.
Luis says Tyshawn is responsible.
The next day, the detective interrogate Luis again, this time he has pictures of his family.
Luis starts to cry.
Luis begins to confess what he says is the truth.
He says he didn't mean for it to happen.
3 am that morning Luis says he ran in to Tyshawn out side and they began talking about the problems he was having with his wife.
Luis says that he and Tyshawn went in Luis' house to play video games because that bothered his wife.
He says that Yessenia comes into the living room and starts yelling at Luis and Tyshawn to get out of the house, to leave.
He said that they started arguing and she grabbed him on the back.
He says that he got her off him by hitting her in the neck.
She fell to the floor grabbing her neck.
He said she stopped breathing.
She died looking at him.
He said the kids then came out of their rooms because of the screams.
Luis told Tyshawn to take them.
Tyshawn took them to a room.
He then hears a "pop, pop, pop."
He went in the room where Tyshawn had taken the kids and the kids were dead and there was blood everywhere.
Tyshawn then took the kids to the bathroom, he had an ax in his hand.
He told Luis said he couldn't go to jail.
He said Tyshawn got rid of the bodies, but wouldn't tell Luis where they were.
Police don't believe his story.
The blood evidence didn't match the police say.
Yessenia's blood was on the mat and the toe of the boot and twelve different places in the master bathroom where there was at least three separate violent acts took place against Yessenia.
Police sit down, one final time to ask Luis what he did with the bodies on October 26.
During the interview, Luis goes several times to the bathroom because he says he is sick.
The last time he goes to the bathroom he said he will never tell where the bodies are.
He then goes in the bathroom and barricades himself in, breaks the glass in the mirror and begins to cut himself.
The police break down the door and tasers him.
Luis survives.
In one a letter from jail, Toledo wrote to a friend, "I sent three boxes to Laredo Texas. 

One large and two small. 

The large was already sent to Veracruz, Mexico and the two (others) are doing well. 

Now you know why I don't care what they do with me because my things are well." 

In the same letter to his friend he wrote that he wished he could tell him what had happened the night Yessenia and the children disappeared, but he couldn't because it could be used against him. He mentioned Yessenia's infidelity and said he was hurt by it, and added, 

"I Want You To Know That I Never Hurt Or Touched My Kids In Any Way & Never Could! I Love Those Kids More Than Anything & Still Love Them Till This Day."He was found guilty for second degree murder of his wife and first degree murder for the kids.
He has to serve three consecutive life sentences.
During his sentencing, Luis flashed gang signs meaning "Just do it."
Yessenia was attending Rollins College in Winter Park, Florida and was projected to graduate with honors in the spring of 2014 with a bachelor's degree in organizational behavior.
After her disappearance, Rollins College awarded her the degree posthumously.
