A convicted killer escaped from an Ohio prison farm in 1959, then was allowed to slip away from law enforcement in 1975 and disappeared until a ruse to get his fingerprints led to his arrest in Florida this week, investigators said Tuesday.

Former Akron, Ohio, resident Frank Freshwaters, now 79, admitted his true identity when authorities confronted him Monday, according to the U.S. Marshals Service and deputies in Brevard County, Florida.

Marshals in Ohio had sought help from deputies there, and they created a ruse to get him to sign papers so they could check his fingerprints, which matched the decades-old arrest, said Major Tod Goodyear.

"We couldn't go with a picture and see if it's that guy," Goodyear said. "You look different than you do 50 years ago."

An old picture of Freshwaters came into play, when, after a week of surveillance, they confronted him with a question as he left his trailer in a rural area near Melbourne: Have you seen this man?

"They showed him the pic, and he said he hadn't seen that guy in a long time," Goodyear said. "Then he admitted it and basically said, 'You got me.'"

The man sent to the Ohio State Reformatory in 1959 had short, dark hair in his black-and-white mugshot. Now he has a white beard, a ponytail and glasses and lived in a weathered trailer in a remote area surrounded by palmettos and very few neighbors.

"It's a nice place to kind of hang out by yourself if you don't want people to know you're there," Goodyear said.

He had retired from a job as a truck driver and was living off Social Security benefits, Goodyear said.

He'd left clues about his identity over the past 56 years, and investigators traced those to his Florida doorstep, said U.S. Marshal Pete Elliott in Cleveland. He wouldn't discuss specifics.

"We have a saying in the Marshals Service, 'Let no guilty man escape,' and that is so true in this case," Elliott said.

Freshwaters was convicted of manslaughter for killing a pedestrian with a vehicle in July 1957, and his initially suspended sentence of one to 20 years in prison was imposed in 1959 after he violated his probation by driving and getting a driver's license, according to the marshals and old court documents they provided. He was imprisoned at the old Ohio State Reformatory before being moved to a lower-security camp near Sandusky, where he escaped in September 1959, the statement said.

His time on the lam was interrupted in 1975, when he was arrested on the Ohio warrant by the sheriff's office in Charleston, West Virginia. When the governor there refused to send him back to Ohio, he was freed and disappeared again, the marshals said.

An investigation by a deputy marshal assigned this year to target cold cases led authorities to Florida, where Freshwaters was living as William Harold Cox, the statement said.

The Brevard County Sheriff's Office said he was jailed under the name Harold F. Freshwater and was ordered held without bond because of his status as an out-of-state fugitive. Court records listed no attorney for him as he awaited a hearing about possible extradition to Ohio.
