Her Mother Was Murdered And She Was Kidnapped And Never Found.

Dennise Sullivan

She was 15 years old when she went missing from Moab, Utah on July 4th, 1961.

She was on vacation with her mother and her mother's finance from Rockville, Connecticut.

There was a man on the side of the road having car trouble near Dead Horse Point.

After the man flagged them down they pulled over to help.

After they stopped, he pulled out a .22-caliber rifle and demanded money.

Jeannette Sullivan threw $250 on the road, made some comment about the man and turned to get into her car when she was fatally shot in the back of the head.

The man shot her finance, Charles Boothroyd, in the face twice. 

He left for dead, but he survived to tell officers about the crime.

Denise, had stayed in the car. 

She started the vehicle and tried to drive away.

The gunman chased her down in his car, forced the car off the road and kidnapped her. 

Her body was never found.

About 10:30 p.m. on July 7, 1961, lawmen stopped Able B. Aragon car at a roadblock at Crescent Junction.

He was a 35 year old, unemployed WWII Marine Corps veteran from Price who had earned the Navy Cross. 

He was known as a nice guy and a family man. 

He was missing, and his license plate matched the partial number that was reported.

When an FBI agent tried to question him, he shot himself in the head with a pistol. 

Denise Sullivan and the .22-caliber rifle were not in the car.

He was transported to the Moab hospital, but died two hours later.

Attention now was on a remote area called Polar Mesa.

It is a uranium mining camp near the Colorado border. 

A cook at Polar Mesa told officers she had talked to Able, who had been camping there.
At the camp, officers found clothes belonging to able hidden under a bush, along with the .22 rifle and a short-handled shovel.

There was no sign of the missing teenager.

There were a lot of ore mines down there, some of which were searched, but there was no sign of Dennise.
