Magno Sosa, 32, of Nantucket was killed on Elmwood Street in Everett, Massachusetts in the early morning of January 17, 2015. Police responded to reports of a disturbance just before 2 a.m. and found Sosa with multiple gunshot wounds to the head; paramedics pronounced him dead at the scene.

Investigators tied the shooting to an earlier altercation. Around 1:00 a.m. Sosa had been at an apartment on Main Street in Everett with two other men and 26-year-old Rigoberto Escobar. A physical fight between Sosa and Escobar prompted the apartment resident to ask them to leave. The argument continued outside and escalated from a fistfight to a shooting.

Escobar was arrested in the hours after the killing. Police say the firearm used was later recovered wrapped in a shirt and hidden in a rolled-up rug in a basement, and that Escobar’s fingerprints were on the weapon. Does anyone have information about the events that night or knew Magno Sosa?
