TOLEDO, Ohio (AP) -- Ohio authorities investigating the fatal prison beating of a serial killer dubbed the "Angel of Death" say they're in no hurry to file charges.
A spokesman for the State Highway Patrol says that's because the suspect already is behind bars.
It's been nearly two months since Donald Harvey died after he was beaten at the state prison in Toledo.
