A 34-year-old accused hit-and-run killer is set to be arraigned next week on murder and other charges stemming from a deadly crash in Palmdale that killed two people, including a 17-year-old boy.

Relatives of the victims hugged and cried outside the sheriff’s station after the suspect’s arrest, with one family member asking that people “just don’t forget about them” and several others thanking the community for sending in tips.

William Alexander Marquez is charged with two felony counts each of murder, vehicular manslaughter with gross negligence and hit-and-run driving resulting in death or serious injury to another person, along with one misdemeanor count of hit-and-run driving resulting in property damage.

The charges stem from a crash about 10:20 p.m. on Jan. 30 near 10th Street West and Avenue O-8. Albert Cruz, 17, and Sergio Martinez, 18, both died at the scene.

Two other people were hurt, but declined to be transported to an area hospital, according to the Los Angeles County Fire Department.

Marquez was allegedly speeding away from an earlier crash at Rancho Vista Boulevard and 10th Street West when he crashed into a vehicle carrying the fatally injured victims, then fled on foot, according to Los Angeles County sheriff’s Detective Danielle Day.

Marquez — who had publicly been named as the suspect — surrendered Feb. 5, according to the detective, who said the victims were “great kids, and it shows in how many people wanted to help” by sending in tips to help detectives identify and locate the driver.

Marquez was released on $50,000 bond the day of his arrest, jail records show.
