Two Folsom Prison inmates sentenced in San Diego County for assaults are suspected of killing another inmate while in the prison recreation yard, authorities said Sunday.

Officials identified the two prisoners who allegedly attacked Nathan Marcos as Tyler Yates and Gregory Roach.

Yates, 27, was sentenced in San Diego County to eight years in state prison in 2017 for burglary and assault.

Roach, 33, was sentenced in San Diego County to 12 years in state prison in 2019 for assault.

Marcos, 33, was set upon by two other inmates at 2:12 p.m. Saturday. Prison staff used chemical agents to stop the attack, according to officials from the California Department of Corrections and Rehabilitation.

Marcos was declared dead almost a half hour later.

The victim received a four-year sentence in San Joaquin County in 2013 for evading a peace officer and possession of a controlled substance for sale. Then he was sentenced in 2016 in Kings County to six years for possession and manufacture of a deadly weapon by a prisoner as a second-striker.

Prison officials moved Roach and Yates to a segregation unit pending an investigation. Folsom is a high-security site about 20 miles northeast of Sacramento.
