Somerville Police Detectives, working with inves...tigators from the Medford Police Department and the FBI Violent Crimes Task Force, began to follow leads which quickly associated the Evergreen Avenue incident, with a stabbing that was reported in Medford about thirty minutes after the Evergreen Avenue incident. Working together, the investigators were able to connect the two incidents, which resulted in identifying both suspects in the Somerville shooting incident. On December 5th, Somerville Detectives Alex Capobianco and Jonathan Thermidor obtained warrants to arrest Joshua Sullivan, age 18, with a last known address in Somerville and Khyam Mayes, age 29, who is listed as homeless, for armed assault with intent to murder and assault and battery with a dangerous weapon. Both suspects were arrested by Somerville Police this morning.
Chief Thomas Pasquarello praised the work of the investigative team, who quickly solved this violent incident that occurred on a quiet residential street and acknowledged the support of the neighborhood residents, especially the Evergreen Community Alliance.
