BOSTON — Former NFL star Aaron Hernandez was a member of the Bloods street gang and was disciplined for having gang paraphernalia, according to newly released documents related to the investigation into his prison suicide.

A death report released Friday lists the Bloods under Hernandez’s gang profile and says Hernandez was disciplined for having “STG” paraphernalia. In prison, “STG” stands for Security Threat Group, a euphemism for gangs.

Hernandez, a former New England Patriots tight end, was found April 19 hanging from a bed sheet in his cell in a maximum-security prison where he was serving a life sentence for a 2013 murder. His suicide came days after he was acquitted in a 2012 double slaying. Worcester District Attorney Joseph Early Jr. released the report in response to a public records request from The Associated Press.

The filing by prosecutors was part of their opposition to a motion by Hernandez’s appellate attorneys to vacate his conviction under a state legal principle that says convictions can be erased if a defendant dies before his appeal is heard, as Hernandez did. A judge has set a Tuesday hearing.

The documents released by Early say that while Hernandez was housed in a Bristol County jail awaiting trial in the 2013 case he was disciplined for five violations: threatening to kill a correction officer and his family; submitting a urine sample that tested positive for a painkiller; committing an aggravated assault; refusing to obey an order; and possessing gang paraphernalia.
