WARREN, Maine (AP) An inmate has pleaded not guilty to killing his cellmate at a minimum security prison in Maine.

Zachary Titus made a brief appearance in court on Monday. A separate hearing will be held within five days to determine whether Titus will be eligible for bail in 18 months when he completes his current prison term for theft.

Dana Bartlett died June 24 at the Bolduc Correctional Facility, a minimum security facility in Warren. His fiancee says he was having issues with another inmate and had asked to be moved.

Defense lawyer Jeremy Pratt said Monday that he couldn’t comment because the state had provided no information about the killing, including the autopsy or affidavits.
