"As far as I know she never had any criminal history after she came here," Giles County Sheriff Kyle Helton told reporters. "She never got into any trouble. She led a flawless life."
Darby was convicted in 1970 of the shooting death of her husband in Hammond, Indiana. The body of Charles R. Darby was found in the bedroom of their home which had been set on fire and smelled of gasoline and kerosene.
Linda Darby was sentenced to life in prison but climbed over a barbed wire fence in 1972 and escaped from the Indiana Women's Prison.
"I'm not a murderer," Darby told WSMV-TV. "I just don't know how they ever convicted me. I really don't. But I didn't do it."
Darby's arrest came two weeks after the formation of the Indiana Department of Correction's new Indiana Fugitive Apprehension Unit which hunts for offenders who have escaped from prison, work release or parole.
