CRANSTON, R.I. (WLNE) -  Correctional Officer and RI Brotherhood of Correctional Officer President Richard Ferruccio says John Carillo has always been a violent, problematic inmate.

He was held on bail Tuesday for allegedly stabbing correctional officer Jason Messier on Friday. But he's already serving a life sentence for stabbing to death correctional officer Donald Price in 1973.

"He’s been doing time since the 70’s and you know what, he’s got nothing to lose. And that's the real problem that we see."

Messier was able to escape serious injury. But others aren't always so lucky. According to Ferruccio, about 50 correctional officers at the ACI are seriously hurt every year.

Some are a result of direct attacks on officers. But more often, they get hurt trying to break up fights amongst inmates. Those are becoming more common since the closure of an ACI building - ironically named after Donald Price.

"Rhode Island being a small state...the enemy issues are pretty serious. You have guys that have killed family members and friends and gang members of one another, and now they're forced to live together.”

And during a lockdown over the weekend, investigators found even more weapons stashed in common areas. Ferruccio says officers are on high alert.
