Two restaurant employees were fatally shot at the Wingstop at 528 Lake Park Ave., near Lake Merritt, at about 11:45 p.m. Monday, according to police.
Investigators have identified the victims as 26-year-old Jose Santa Maria and 22-year-old Kenneth Bradley, both residents of Richmond.
Officers responded to the eatery after being alerted of an alarm activation there, police said. They found the two employees with gunshot wounds, and both were pronounced dead at the scene.
Whent said the shooting happened inside the restaurant.
Investigators initially said the killings may have occurred during a robbery, but Whent said that does not appear to be the case, based on surveillance video footage and witness statements.
A suspect in the double murder was taken into custody just before 8 a.m. today in West Oakland, Whent said.
Police have not released a description of the second suspect. Police are planning to hold a meeting with area merchants to discuss crime prevention and community involvement, but have not yet announced a time or location.
