A man who was shot and wounded in an incident that left another man dead Monday morning in Woburn, Massachusetts, appeared in court Tuesday as the investigation continued.
Two men were shot during the incident at the Washington Street residence — 22-year-old Mussie Nirayo, who was pronounced dead on scene, and 26-year-old Tyler Olivier, who was taken to a hospital, later arrested and is now facing charges, according to prosecutors.
Olivier faced a Woburn District Court judge for an arraignment on charges of possession of a firearm and assault and battery with a dangerous weapon Tuesday.
His attorney said he acted in self-defense during a home invasion.

He was ordered held on $50,000 bail and is expected back in court March 28.
But Olivier is facing other charges from 2021 and 2022, including accusations of stabbing a man and a pregnant woman and violating a restraining order. The judge revoked his bail in those two cases.
Police Called to Woburn, Mass. Home for Report of Disturbance
Officers with the Woburn Police Department responded to the home on Washington Street for a report of a disturbance at around 3:40 a.m. on Monday, according to a news release issued by the Middlesex County District Attorney's Office on Monday night.
When police got to the home, they found the two men with apparent gunshot wounds. Nirayo, who was pronounced dead, was found wearing a mask with a gun in hand.
Court documents state that Olivier told officers he knew Nirayo, but that he later said he didn't. An earlier press release from police said the two men knew each other, but later Monday night, prosecutors said an investigation into whether they knew each other was ongoing.
Ongoing Investigation by Mass. Authorities
The investigation into the shooting remained ongoing, and involved several law enforcement agencies, including the Middlesex County District Attorney's Office, Massachusetts State Police detectives assigned to that office, as well as the Woburn Police Department.
The prosecutors who have been assigned to the case were Graham Van Epps and Jacob McCrindle.
Tyler Olivier's History
Sources told the NBC10 Boston Investigators earlier Monday that Olivier was the man who survived and that he was accused in 2021 of slashing and stabbing a man and a pregnant woman. That crime also took place on Washington Street.
