Jessica Martinez, 24, of North Hollywood, pleaded not guilty Tuesday to charges of murder and hit-and-run driving resulting in death after a crash on June 6 that killed 20-year-old Anthony Chay in North Hollywood.

The collision occurred at 5:25 a.m., when Martinez was driving at “high speeds” southbound on Vineland Avenue, according to the Los Angeles Police Department. Her red Audi A4 rear-ended Chay, who was stopped on his motorized scooter at a red light at Vineland and Vanowen.

The crash ejected Chay from his motor scooter onto the street, according to the LAPD. Then, Martinez’s vehicle continued to hit other parked vehicles before stopping and catching on fire. She was then treated and transported to a local hospital by the Los Angeles Fire Department for minor injuries.

A GoFundMe has been set up for Chay’s mother.

Martinez is scheduled to return to court Tuesday, June 25.
