ON EVE OF TRIAL, MAN PLEADS GUILTY TO 2003 HOMICIDE March 11, 2008 A 20-year-old Dorchester native facing trial for the 2003 shooting death of an acquaintance pleaded guilty to the crime and was sentenced to up to 18 years in state prison, Suffolk County District Attorney Daniel F. Conley announced. BRIAN MAYES (D.O.B. 2/17/87) pleaded guilty yesterday to the crime of manslaughter for the Sept. 12, 2003, fatal shooting of 24-year-old Gary Sanon near the intersection of Harvard and Radcliffe streets in Dorchester. Sanon, who was 16 at the time of the incident, accepted a sentence of 15 to 18 years in state prison. Had the case proceeded to trial, Suffolk prosecutors would have demonstrated that Mayes and Sanon were associated with female residents at a Vesta Road apartment building during the summer of 2003. Prosecutors would also have shown that Sanon had a .22 caliber firearm that was stored at the apartment and that Mayes found and kept it. Sanon confronted Mayes about the firearm, sparking a series of arguments between the two men. Those arguments reached the boiling point on the morning of the incident, when Mayes shot Sanon multiple times, killing him. He was identified as a suspect after the gun, which was used in another crime, was recovered at the Vesta Road residence in the course of that investigation. Mayes was represented by attorney E. Peter Parker. Return to the Press Releases page.
