Mussie Nirayo, 22, was shot and killed in a Woburn, Massachusetts home during the early hours of February 20, 2023. Police responding to a disturbance call on Washington Street around 3:40 a.m. found two men with gunshot wounds; Nirayo was pronounced dead at the scene and a 26-year-old man, Tyler Olivier of Woburn, was taken to hospital. Investigators said the men were known to each other and the shooting was not considered random.

Olivier was arrested on charges of firearm possession and assault and battery with a dangerous weapon, though no murder charge was announced immediately. At Olivier’s arraignment his attorney claimed self-defense, saying Olivier shot Nirayo and another person who were breaking into his residence; court filings noted Nirayo was found with a firearm in his hand. Nirayo’s family describe him as charismatic and generous and have set up a GoFundMe as they grieve.

Does anyone have information about what happened in that Washington Street home that morning?
