From [HERE] and [HERE] Enrest "Marty"Atencio is at least the 12th inmate to die under strange circumstances in the Maricopa County jail system. (The Phoenix New Times lists 11 other such cases here.) And listing “law enforcement subdual” as one cause of death, according to former Maricopa County chief prosecutor Rick Romley, is particularly unusual because it could implicate law enforcement in Atencio’s death. 

The former soldier’s allegedly rough treatment by officers at Arpaio’s infamous Fourth Avenue jail in Phoenix was caught on routine jail video tape. By then, Atencio had been in police custody for over four hours and had been showing signs of “acute psychosis,” the medical examiner reports. The video appears to show burly officers from Phoenix and Maricopa County piling on Atencio, apparently after he said something, though exactly what remains unclear because jail cameras don’t record audio.

Atencio was  subdued for seven minutes, according to the medical examiner’s report, which found evidence of “apparent carotid chokehold, prone placement and restraint, use of conducted electrical device and use of handcuffs” on Atencio’s corpse. He was eventually checked by a jail medical employee before being carried to a cell, where he was stripped naked and lay completely motionless except for an “unspecified movement in his abdominal region,” the report continues.
