WASHINGTON, April 5 (UPI) -- The FBI has been looking for patterns in killings along U.S. highways, suspecting that some long-haul truck drivers are responsible for many of them.
The victims include prostitutes, hitchhikers and women whose cars have broken down, the Los Angeles Times reported Sunday. Agents working out of an office in Virginia study killings, looking for patterns.
"You've got a mobile crime scene," one investigator said. "You can pick a girl up on the East Coast, kill her two states away and then dump her three states after that."
The Highway Serial Killings Initiative began five years ago after an analyst with the Oklahoma Bureau of Investigation asked the FBI for help with a string of seven killings of prostitutes along I-40. An FBI analyst going through the bureau's data base found killings that matched the Oklahoma crimes.
A truck driver, John Robert Williams, 28, confessed to some of the Oklahoma killings and others. While he later recanted, agents say he gave details only the killer would have known.
He described killing one woman who solicited him for sex at a truck stop in Indiana.
"The second she tapped on my window, she was a dead woman," he allegedly said.
