The Somerville News
The man who allegedly shot a decorated Somerville police officer before being fatally shot himself by police was sought for arrest by police and the Federal Bureau of Alcohol, Tobacco, Firearms, and Explosives, Middlesex County prosecutors said today.
Matthew Krister, 21, was pronounced dead after being transported to Somerville Hospital after the shooting at about 6:40 p.m. Tuesday night.
Officer Mario Oliveira is in stable condition at Massachusetts General Hospital, said the Middlesex district attorney's office, which is investigating the shooting.
Somerville Deputy Police Chief Paul Upton said Oliveira was about to celebrate his 10th year on the force. He said Oliveira was currently assigned to a task force with the federal firearms agency. He was one of three Somerville officers who work regularly with federal law enforcement agencies.
Upton said Oliveira is a highly decorated officer who has earned a reputation for doggedness as an investigator who has deep empathy for the crime victims he has encountered over the years.
"Let me put it this way, if something bad happens in your family, Mario is the guy you want to see show up,'' Upton said this morning. "He is a bulldog."
Mayor Joseph A. Curtatone told the Globe Tuesday night that after Oliveira was shot three times, other officers opened fire.
