Ohio detective brings down ‘Ladykiller’ Shawn Grate with 33-hour interrogation: ‘A hunger to kill’

When Kim Mager sat across from Shawn Grate, she was expecting to interact with another sex offender, one of many from her decades-long career.

Mager, a 30-year veteran of the Ashland City Police Department in Ohio, had no idea she was face-to-face with a serial killer. She interrogated him for 33 hours over eight days.

"When I first started speaking to him, I didn’t find his personality to be that far off from other sex offenders, and I’ve interviewed many sex offenders," the retired detective told Fox News Digital.
