A Windsor man has been sentenced to life in prison, with no chance of parole for 15 years, related to the death of his former girlfriend’s mom.

Richard Scott Raymond, 28, pleaded guilty in September to second degree murder of Carol Shaw, 49, at a Bruce Avenue apartment on Feb. 23, 2015.

Raymond was previously charged with first degree murder and aggravated sexual assault.

Police said Shaw died of restricted blood flow and blunt force trauma.

Court heard after drinking a significant amount of alcohol, Raymond went to Shaw’s apartment to purchase oxycontin.

But Raymond’s lawyer, Brian Dube, says his client doesn’t remember that night.

“The last memory he has is of leaving with his girlfriend from her uncle’s place” said Dube. “His next memory is his next couple of hours after the incident where he's in the hospital waking up and being treated by staff there."

Members of Carol Shaw's family delivered powerful victim impact statements in court on Monday.

Shaw's daughter said “I cry to myself, I wonder, why her? I would give anything to have her back."

In delivering the sentence, Justice Renee Pomerance said “it is apparent from the facts Ms. Shaw was terrorized by the attack. It's hoped these proceedings will provide some measure of closure."

Raymond, 28, admits to a history of substance abuse and is diagnosed with a bipolar disorder. He did address the courtroom Monday saying “I realize how bad it was. I'm truly sorry for it. I want to make something of my life in the future."
