An inmate who was stomped to death after he cut in front of two gang members in a dinner line at the Men’s Central Jail had mental problems and was incarcerated for a nonviolent offense, authorities said. Sheriff’s officials said Friday that 35-year-old Chadwick Cochran had been in downtown’s Twin Towers mental health facility last month but was eventually moved into the general population at the Men’s Central Jail, where many violent inmates are housed. “He was a fish out of water,” Sheriff Lee Baca said. “These inmates were sharks, and he was in the shark tank.” Authorities are investigating why he was moved from one facility to the other. Cochran never used the weapon or threatened anyone with it. When deputies arrived, he apparently had given the gun back to Rowe, according to court documents.160Want local news?Sign up for the Localist and stay informed Something went wrong.

The men were among 30 inmates locked in a room to eat dinner while deputies searched nearby cells for weapons. The inmates were left alone and unsupervised. The death was the eighth in the county jail system in two years. Christian Perez, 18, and Heriberto Rodriguez, 24, were later charged with murder. Friends told authorities that Cochran was a transient who suffered from paranoia and delusions. He ended up in jail after a series of events that began in October when 79-year-old Gloria Mae Rowe of Covina befriended him after finding him in the rain outside a supermarket near her home. Because Cochran was worried about people trying to “get” him, Rowe said she lent him a loaded black revolver. Sheriff’s deputies arrested Cochran after discovering the gun, possession of which was a violation because he had been convicted of a robbery 14 years ago.
