A Dade County, Ga., inmate was found dead in his cell 14 minutes after being jailed for driving under the influence of alcohol, authorities said.

A detention officer found Joseph Cochran, 29, dead at 4:40 Tuesday morning, Sheriff Patrick Cannon said. Authorities believe Cochran used his thermal underwear to hang himself, Cannon said.

Cochran had been arrested earlier in the morning and charged with DUI. He was in the holding cell when he was found, Cannon said.

"It's a sad situation," the sheriff said.

Officers tried to revive Cochran by performing CPR, but he was already dead, Cannon said. The Georgia Bureau of Investigation was called in to investigate, a standard procedure.

An autopsy and toxicology report will be performed as required in the death of any Georgia inmate, Dade County Coroner Johnny Gray said.

Cochran was a Marine and had served several times overseas, Cannon said.
