ESCONDIDO, Calif. – A 28-year-old woman who police say was the driver of a vehicle that killed four pedestrians last month in Escondido was arrested Thursday in connection to the incident.

Escondido resident Ashley Rene Williams.

Escondido resident Ashley Rene Williams is being charged with four counts of murder and four counts of gross vehicular manslaughter while intoxicated, police said Thursday. Officers say Williams was driving at about 8:30 p.m. May 5 on San Pasqual Valley Road near Oak Hill Drive when she struck a man, a woman and two boys.

The four victims include Carmela Camacho, 50; Abel Valdez, 33; Yovanny Felix, 10; and Emmanuel Riva, 11, according to police. Valdez and the older child died at the scene. Medics took Camacho and Yovanny to Palomar Medical Center, where they were pronounced dead.

Williams was transported to Scripps Memorial Hospital for treatment of moderately serious injuries.

Calling the case “a devastating event for our community,” Lt. Scott Walters said it took four weeks to make an arrest because investigators had to analyze copious evidence, including cellphone and vehicle computer data, roadway measurements and laboratory test results.
