On December 30, 1950, Texan mechanic Lee Archer was driving his car near
Lubbock, Texas when he picked up Billy Cook, who was
hitchhiking. Shortly afterward, Cook robbed Archer of $100 at gunpoint and forced him into the trunk of his car. Later, Archer escaped by forcing open the trunk with a
tire iron. After the car ran out of fuel between
Claremore and
Tulsa, Oklahoma, Cook posed again as a hitchhiker. This time, he was picked up by farmer Carl Mosser from
Illinois, who was en route to
New Mexico with his wife Thelma, their three young children (Ronald Dean, Pamela Sue, and Gary Carl), and a dog. At gunpoint, Cook forced Mosser to drive around aimlessly for 72 hours. At one point, Mosser nearly overpowered Cook at a filling station near
Wichita Falls, Texas, but Cook was too strong for him. Cook shot the entire family and their dog shortly afterward. He dumped their bodies in a mine shaft near his hometown of Joplin. Cook headed back to California after abandoning the Mosser car in Oklahoma. The car was discovered full of bullet holes and covered in blood. The receipt for Cook's gun was found in it. Just outside Blythe, Deputy Sheriff Homer Waldrip became suspicious of Cook and went to the motel where he had earlier lived with a friend. Hoping to question the friend, he was instead taken by surprise when Cook himself jumped from behind the door and took his
revolver. Waldrip was taken hostage by Cook. As with the Mossers, Cook forced the deputy to drive around aimlessly. During this drive, Cook bragged about murdering the Mossers. After some 40 miles, Cook ordered the deputy to pull over and lie face down in a ditch, saying he would shoot him in the head; however, Cook instead got back into the police car and drove away. Cook then kidnapped another motorist, Robert Dewey, from
Seattle. Sometime later, the traveling salesman tried to wrestle the gun from Cook, but was wounded in the process. The car left the road and careened into the desert. Cook murdered Dewey with a shot to the head. Dewey's body was found in Waldrip's abandoned car near
Ogilby, California; Cook abandoned Dewey's car in
Mexicali, Mexico. By this time, all law enforcement agencies throughout the U.S. Southwest were on the lookout for Cook, who had returned to Blythe. He kidnapped two other men, James Burke and Forrest Damron, who were on a hunting trip. He forced them to drive across the Mexican border to
Santa Rosalía, where he was recognized by the local police chief, Luis Parra, who walked up to Cook, snatched the .32-caliber handgun from his belt, and arrested him. Since Mexico did not have an extradition policy with the United States at the time, a group of officers decided to physically push Cook across the border. He was immediately arrested. Cook was found with a small arsenal after his arrest, which consisted of the
.32-caliber Colt 1903 handgun, a
.38-caliber Smith & Wesson Model 10 revolver & two
bolt-action rifles (a
.22-caliber Remington Model 34 & a
.270 Winchester Model 54). ==Execution==
