Larry William Eyler (December 21, 1952 – March 6, 1994) was an American serial killer who is believed to have murdered a minimum of twenty-one teenage boys and young men in a series of killings committed between 1982 and 1984 in the Midwestern States.
Convicted and sentenced to death by lethal injection for the 1984 kidnapping and murder of 16-year-old Daniel Bridges, Eyler later voluntarily confessed to the 1982 murder of 23-year-old Steven Ray Agan, offering to also confess to his culpability in twenty further unsolved homicides if the state of Illinois would commute his sentence to one of life imprisonment without parole.Eyler died of AIDS-related complications in 1994 while incarcerated on death row.
Shortly before his death, he confessed to the murders of twenty further young men and boys to his defense attorney, Kathleen Zellner, although he denied being physically responsible for the actual murder of Daniel Bridges, which he insisted had been committed by an alleged accomplice in five of his homicides, Robert David Little.With her client's consent, Zellner posthumously released Eyler's confession following the formal announcement of his death.Eyler was known as the "Interstate Killer" and the "Highway Killer" due to the fact many of his confirmed and alleged victims were discovered across several Midwestern States in locations close to or accessible via the Interstate Highway System.
