PINCKNEYVILLE, Ill. (AP) — An 80-year-old man who spent nearly 60 years in prison after being convicted of killing one of three suburban Chicago women whose brutalized bodies were found in a state park walked out of prison Friday.

Chester Weger emerged from Pinckneyville Correctional Center much older than when he was sent to prison in 1961, but he was the same in one respect — maintaining that he was innocent and had been framed by detectives and prosecutors.

“They ruined my life,” Weger said outside the prison gates, the Chicago Tribune reported. “They locked me up for 60 years for something I’ve never done.”

Weger was convicted in the 1960 slayings of 50-year-old Lillian Oetting, 47-year-old Frances Murphy and 50-year-old Mildred Lindquist. The women were hiking together in Starved Rock State Park in northern Illinois when they were attacked. Their remains were found in the park’s popular St. Louis Canyon, which is framed by a scenic waterfall and a 100-foot wall. Each of them had been bludgeoned more than 100 times.

A break in the investigation came when detectives determined that the cord used to bind the women’s hands matched twine from a spool in the kitchen of the Starved Rock Lodge, where Weger, then 21, worked as a dishwasher.

Wegner initially confessed to beating the women to death with a frozen tree branch during a botched robbery attempt and even took detectives to the park to reenact the killings.

But he later recanted, claiming he was innocent and that prosecutors had coerced him into confessing.

Weger was only convicted in Oetting’s killing. Prosecutors chose not to try him for the two other women’s deaths after he was sentenced to life in prison in 1961.

Weger was granted parole in November on his 24th try. His release was delayed for 90 days because Illinois Attorney General Kwame Raoul’s office sought to have him evaluated under the state’s Sexually Violent Persons Commitment Act. That law allows the state to hold people indefinitely in a secured facility in the custody of the Illinois Department of Human Services for sex offender treatment if an evaluation deems that necessary.

Granddaughters of the slain women have spoken out publicly against Weger’s release, as has the LaSalle County state’s attorney. But Weger’s supporters have insisted that he poses no threat to public safety and experts who conducted Weger’s evaluation concluded that Weger did not meet the legal criteria for the law to apply,

One of Weger’s lawyers, Celeste Stack, said Weger could hardly believe he was free.

“Rumors had been floating around that things were going to be delayed,” Stack told the Tribune. “I don’t think even Chester believed it until he stepped outside in this cold sunshine this morning.”

Weger was expected to be reunited with family members later in the day on Friday and then check in to St. Leonard’s Ministries in Chicago.
