A 37-year-old South Seattle woman has been charged with felony hit and run and two counts of second-degree assault, accused of intentionally hitting two Chief Sealth High School students with her car last week following an argument over the woman’s pit bull, according to King County prosecutors.

Amy O’Brien, who surrendered to police on Nov. 29, had her bail reduced from $250,000 and was released from the King County Jail Tuesday on personal recognizance, according to prosecutors and jail records.

According to charging papers, a group of high school girls were walking to school in the 8600 block of 26th Avenue Southwest on Nov. 28 when two dogs ran up to them, including a pit bull. The pit bull jumped on one of the girls, Cassandra Goodwin, who pushed the dog away but upon realizing he was friendly, she and the other girls petted the animal, the papers say.

O’Brien ran out and confronted Goodwin, accusing her of hitting the dog and then trading punches with Goodwin, who repeatedly tried to apologize and explain what had happened, the papers say. The girls called 911 and continued walking to school, but were pursued by O’Brien in her car, according to charging papers. O’Brien got out of the vehicle, threatened the girls with a Taser, then continued her pursuit as the girls ran off, the papers say.

Moments later, O’Brien struck Goodwin and another girl, Jessica Vega, with her car, slamming into the girls at an estimated 40 mph, the papers say. One witness told police the impact caused Goodwin and Vega to be thrown 20 feet in the air, the papers say. O’Brien then fled the scene, according to charging papers.

Both girls were knocked unconscious and were seriously injured; Goodwin’s ear was partially torn off and Vega suffered a concussion, the papers say.

O’Brien is to be arraigned Dec. 17.
