Identified Suspect

The prime suspect in the kidnap/homicide is Abel Benny Aragon. He was an unemployed coal miner. He lived in Price, Utah. His vehicle matched the description of the abduction car. When the FBI stopped him for questioning on July 6, Aragon shot himself in the head with a .22 caliber pistol. He was rushed to the hospital. But died two hours later without regaining consciousness. It was the day after his 35th birthday.

Aragon was a Marine veteran who was awarded the Navy Cross for heroism during World War II. And he had no criminal record. Witnesses reported seeing him alone at 2:00 A.M. on July 5. This was about four and a half hours after the shooting at Dead Horse Point.

Covering His Tracks?

Aragon stopped a truck driver. He gave him an envelope and asked him to mail it. The envelope contained money and a note addressed to Aragon’s wife. It was telling her he loved her and their five children. It didn’t mention any crimes.

Five hours after the shooting, Aragon arrived at a mining camp at Polar Mesa, where he had stayed several times before. When authorities searched the area on July 10, they found some of his clothing. Nearby, under a rock, they found the .22 rifle that had been used in the shooting, and hidden in the brush was a shovel identified as Aragon’s.

Authorities made a determination. They concluded from the paint scratches and other damage to his car that it was the same vehicle that rammed into Boothroyd’s car. It was the same vehicle which forced it off the road. They also found a set of Aragon’s tracks, and a smaller set parallel to them, believed to be Dennise’s. They never found any trace of Dennise herself, however.

Foul play is strongly suspected in Dennise’s case. This due to the circumstances involved. An exhaustive search turned up no sign of her. Her body may be somewhere in the Polar Mesa area.
