(AP) – A Springfield man has been sentenced to life in prison without parole for killing his roommate so he could steal his heroin.

 40-year-old Jarrod Sirois was found guilty in December of first-degree murder in the beating death of 45-year-old Robert Pugh.

Judge Calvin Holden sentenced Sirois on Friday after denying his motion for a new trial.

Sirois told authorities he killed Pugh so he could steal his drugs, with the intention of overdosing on it, July 6, 2012.

Sirois admitted using a metal pipe to hit Pugh in the head three or four times while Pugh was asleep on the couch.

He told police he was only trying to knock Pugh out.
