A woman accused of intentionally driving her car into two teenage students of Chief Sealth International High School was charged with two counts of second-degree assault and one count of felony hit-and-run Tuesday.

Amy Lynn O’Brien left King County Jail around 6 p.m. on conditional release. Her bail had been set at $250,000. The 37-year-old Seattle woman’s arraignment is set for Dec. 17, according to the King County Prosecuting Attorney’s Office.

Witnesses of the hit-and-run told police that O’Brien deliberately rammed into the 17-year-old and 18-year-old girls after she had physically fought with them and chased them with a stun-gun the morning of Nov. 28.

She then sped off and did not turn herself into police until the next day at Seattle Police Department’s South Precinct. She told police the girls had “surrounded” her, according to a police report released Friday by King County prosecutors.┬áPolice spokesman Renee Witt also said O’Brien was angry at one of the victims because she said the girl struck her dog.

The 17-year-old was released from Harborview Medical Center the day of the hit-and-run but her 18-year-old friend stayed there in serious condition. An update on her condition is unavailable after her family requested that the hospital keep it private.
