“What we saw with this particular suspect is that he was walking around with a flashlight looking into every single car, so he’s trying door handles. If the car was locked, he’d break the window,” said San Mateo Police spokesperson Michael Haobsh.

Police say among the stolen items were a wallet, sunglasses, cash and credit cards.

“It’s a nice community, I wouldn’t think that that would be happening, but it’s kind of happening every where,” said Sharon Fernald of San Mateo.

San Mateo Police are urging residents to not leave any valuables in their cars. The thief burglarized both locked and unlocked cars.

“I grew up in Burlingame, so not too far from here, and it was really safe. We did kind of the same thing, left your front door unlocked, left the car unlocked sometimes,” added Fernald. “But I think now in this time period, 2019, people are locking their cars.”
