PORTLAND, Ore. -- An 18-year-old Portland man has been arrested for the murder of Jefferson High School senior Borisshell Washington on Sunday night, police said.
Todd Allen Rutherford was arrested just after 6 p.m. Monday in Northeast Portland.
Washington was shot while attending a barbecue with friends at Raymond Park in Southeast Portland, according to homicide detectives.
Police suspect the shooting was gang related.
Rutherford was being held on one count of murder in Multnomah County Jail.
Girl killed one week before graduation Washington was found in the park around 9:30 p.m., near the SE 118th Ave. and Schiller St. intersection, after police received reports of gunshots in the area.
She died one week before graduating from Jefferson High.
"Ms. Washington had attended the gathering in the park along with many other people," Portland Police Bureau Detective Mary Wheat said.
Neighbors said that "fights" quickly broke out at the party.
Washington had already lined up summer work as a model and planned to attend cosmetology school, said Angelina Logan, the victim's sister.
"She was doing [well]. She was about to go to college. She was graduating and everything. She didn't do anything to anybody.I don't know why it had to be her," Logan said.
A small, newer model, dark-colored vehicle was seen leaving the scene at a high rate of speed directly after the shooting, witnesses told police.
Investigators are following up on all leads in this case. No motive had been revealed and police would not comment on whether the shooting may have been gang related.
Anyone with information about this case should immediately contact Detective Ken Whattam with the Portland Police Bureau at (503) 823-0696.
