Somerville Police Department
In April of 2010, Detective Mario Oliveira was assigned to the ATF Task Force where he has been involved with the recovery of over forty stolen handguns and several arrests. On November 2, 2010 the team was conducting surveillance at a suspect's home who was known for running guns for gang members. When the suspect left the residence and got into his car Detective Oliveira, with his gun drawn, approached the driver's side of the vehicle and identified himself. At the same time an ATF agent approached the passenger side and a police officer approached the rear of the car. Immediately the suspect looked like he was getting out of his car, instead he opened fire hitting Detective Oliveira five times knocking him to the ground. The backup police officer and ATF agent returned fire striking the gunman and ending the threat.
