Police are looking for a gunman who opened fire at an adult Halloween party that was being held in a parking lot in East Palo Alto.
Two people were killed and two others were hurt, suffering from life-threatening injuries.
It happened early Sunday morning in the parking lot in front of A-1 Auto Service and Towing in the 2500 block of Pulgas Avenue at around 2:44 a.m.
People were out there Monday removing some of the decorations that were set up for the event.
The owner of the towing service says the party was for his daughter.
Police say there was some sort of argument just before the shots rang out.
One of the people killed was 22-year-old Eduardo Alvarado Sandoval, of Stockton. The other person killed has not been identified.
No word yet on any suspect description.
