San Mateo County sheriff's deputies collected more than 400 guns for destruction at a gun buyback event on May 5, according to the sheriff's office.
The anonymous buyback took place at 1402 Maple St. in Redwood City. All firearms will be destroyed after they are processed, the sheriff's office said.
Residents turned in 427 firearms, including several assault rifles. They received up to $100 in cash for a handgun, shotgun or rifle and up to $200 for an assault rifle.
The gun buyback program was organized by a citizens group and funded in large part by donations from San Mateo County cities and towns, including Menlo Park, Portola Valley and Woodside.
