CONCORD -- Karlo Agustin said he wasn't angry, just resigned to the fact that his day had become more expensive. Dan Zywicki didn't seem too ticked off, either, even though he was stuck changing all four of the tires on his daughter's car.

"You just have to bite the bullet," Zywicki said of the turn of events that had him fixing his daughter's vehicle. "You either laugh about it or you cry."

Nobody was crying in Concord's Valley district, but nobody was laughing, either. Not after police said the tires on about 60 vehicles were slashed by vandals in the areas of Glazier Drive, Bel Air Drive and Machado Drive early Sunday morning.

Police said they began receiving calls from vehicle owners just after 7 a.m. Sunday, with many saying all four of their tires had been slashed, Lt. Tim Runyon said. A majority of the vehicles hit were in the Galindo Creek condominium complex, where residents said several vehicles suffered the same fate in 2010.

"I don't know that I'm angry," said Agustin, 33, a loan officer who works out of his home. "Having gone through this before, you just realize that there's not much you can do. You feel a little bit of shock and then resign yourself to the fact that it's probably gonna cost at least $300 to get it fixed."

Police said they don't know what type of tool was used to slash the tires and that no other details would be released, pending further investigation.

According to residents, a security officer was once on patrol at the complex, but the homeowners association ended that because of the cost. The next homeowners association meeting is scheduled in March.

Underground, gated parking is available at the complex but not for every vehicle, residents said.

Police said they don't have any suspects. Anyone with information is asked to call the investigative division of the Concord Police Department at 925-671-3030 or the department's tip line at 925-603-5836.
