COUNCIL BLUFFS, Iowa (AP) -

Authorities say a Council Bluffs man has committed suicide in his county jail cell.

Pottawattamie County Sheriff Jeff Danker says Shawnessey McKnight cut his neck with a razor Wednesday night at the county jail. Danker says McKnight also did pushups before and after in an effort to pump his blood out faster.

The staff had given the 43-year-old McKnight a razor for shaving. Inmates have the razors for 15 minutes before guards collect them.

Another inmate in the cell noticed McKnight's condition and alerted staff. Danker says McKnight fought off staff who tried to treat him, and he had to be handcuffed and shackled before being sent to a nearby hospital where he later died.

McKnight was being held on federal charges of conspiracy to distribute methamphetamine and counterfeiting.
