On Saturday March 14, 2015, at 11:53 p.m., Portland Police officers responded to the report of a large party of teens letting out of the East Portland Community Center, located at 740 SE 106th Avenue. The Community Center is across the street from the Police Center.

Officers inside East Precinct Police Center could hear people pounding on the front doors and windows of the precinct. Two officers went to the front doors of the precinct to see what was happening outside and just as they opened the doors, they heard gunshots and a 17-year-old male ran inside asking for help, saying he’d been shot at by someone.

Seconds later, the officers saw an armed teen fire another shot towards the South (not towards police) as he walked by the front doors of the precinct. The suspect was walking with a large group of teens as he walked northbound towards Stark Street. Officers shared suspect information via radio and followed at a distance until cover officers could arrive and take the suspect into custody after he got rid of the gun. Officers located and seized the gun as evidence.

Officers from Central and North Precincts and the Gang Enforcement Team (GET) responded to assist with preserving the crime scene and managing the crowd of unruly teens. Officers located one suspected bullet strike on the front of the precinct.

The suspect, 16-year-old Dontae Eugene Mathis Jr., was arrested and lodged at the Donald E. Long Juvenile Detention Hall on charges of Attempted Murder (Measure 11 crime), Attempted Assault in the First Degree, Unlawful Use of a Weapon, and Discharging a Firearm in the City.

GET investigators believe both the suspect and intended victim are involved with rival gangs.

Investigators believe that many eyewitnesses may have left the scene without talking to police.
