updated: Man hospitalized after suicide attempt at Washtenaw County Jail

Sheriff's officials said the 26-year-old man jumped "head first from the second tier" of cells in a medium-security area, resulting in a 13-foot drop.

The man landed on his head and suffered what officials called "significant head trauma," and he had no pulse.

Jail staff administered First Aid and established a pulse, then Huron Valley Ambulance transported him to St. Joseph Mercy Hospital. He's had surgery and remains in critical condition.

Clayton said jail officials had no previous indication the man posed a risk to himself and the man had no history of harming himself.

"This investigation is ongoing, but at this early stage all things point to him attempting to commit suicide," spokesman Derrick Jackson said in an email. "No foul play is suspected."

The suicide attempt occurred at about 8:15 p.m. in a housing block during a time that inmates were out of their cells and permitted to move freely, Clayton said.
