The incident occurred just after 1:30 p.m. on one of the prison’s maximum-security yards when two inmates attacked the victim with an inmate-manufactured weapon. Officers quickly intervened using chemical agents to quell the attack.

The inmate’s next of kin has been notified.

No staff members were harmed in the incident.

Both inmate attackers have been transferred to HDSP’s Administrative Segregation Unit pending the investigation.  

Inmate movement has been limited to facilitate the investigation.
