A Cambridge man pleaded guilty Tuesday morning to manslaughter in connection with the death of a Brian Fahy, 28, of Weymouth, Middlesex District Attorney Gerry Leone said.

Christopher Toppi, 29, whose home is listed on Walden Street, pleaded in Middlesex Superior Court in Woburn, followed by Judge Diane Kottmyer sentencing him to 15 to 18 years in state prison.

“This is a case where the defendant resorted to a seriously violent physical assault to settle differences,” Leone said.

According to authorities, at about 3:28 a.m. Aug. 28, 2010, Medford police and EMS responded to a call to 382 Salem St., Medford, and found the victim bleeding from his head and nose. He was pronounced dead at the scene — the results of Toppi starting a fight with him and beating him to death. An autopsy by the Office of the Chief Medical Examiner blamed blunt force trauma to Fahy’s head.

Authorities got an arrest warrant for Toppi, but he turned himself into Medford police that same evening. He was arraigned Aug. 30, 2010, in Somerville District Court, where he first pleaded not guilty and Judge Neil Walker held him without bail, and he was indicted by a Middlesex Grand Jury on Sept. 30, 2010. At his Oct. 6 arraignment he was again held without bail.
