Police in Orem and Provo report 16-vehicles were broken into on Saturday and Sunday.
"For some reason it spiked." says Ssgt. Matt Siufanua of the Provo police department. "We're not sure why. but with vehicle burglaries they go up and they go down. and this week-end was a bad one for us."
It was a bad day for Diana who didn't want her name used.
Her vehicle was broken into while parked in her driveway.
"They didn't take the radio. they didn't take the tires out of the trunk," says Diana.
All they wanted was her car seats.
"Nobody has car seats like these in the salvage yards," she says.
She learned her vehicle is no longer manufactured and replacement parts are rare and expensive.
Now she'll have to make do with a pair of seats from a different model of car.
"It's a little unnerving.obviously it was something for the car," she says. "I'm not working and I don't have income enough that I can just replace those seats."
The woman was one of 16-car owners who were victimized.
In Provo, police soon learned owners of vehicles left their cars unlocked, making it easy for burglars.
"I think it just comes down to being smart (and) being a hard target," says Sgt. Siufanua. "Being a hard target means take everything out of the car, lock your car doors and don't be an easy victim."
And that's what happened to Dianne. She became an easy target when she failed to lock her doors.
She blames it on the weather.
"My car was unlocked because ... it can freeze in the winter and I can't get into my car," she says.
