TOLEDO, Ohio (AP) - A man already serving a life sentence for killing three teenage girls and a Bible studies teacher in Ohio 14 years ago has received another life term for strangling a fellow inmate. A judge in Toledo sentenced 44-year-old Lawrence Michael Hensley of Sidney on Friday on his guilty plea in the strangling of 24-year-old Brad Hamlin at the state prison in Toledo last year. Hamlin was serving five years for burglary, breaking and entering, and theft in Portage and Cuyahoga counties in northeast Ohio. The victim's mother questioned in court why the killer was locked up with non-violent criminals. Hensley was sentenced to life in prison in 2000 after admitting that he killed four people in Shelby County, 40 miles north of Dayton.
