Some Black Friday shoppers in Kennewick got an unwelcome surprise when they returned to their vehicles and found thieves had stolen their recently purchased items.

Four thefts from vehicles were reported Friday to Kennewick police, and two additional car prowl cases were reported Saturday and Sunday in residential neighborhoods, said Sgt. Ken Lattin.

Some items stolen included a 40-inch flat screen TV, a Garmin GPS unit and new clothes.

In the four thefts in store parking lots, the items were left out in plain view, Lattin said. The thieves either broke a window to swipe the goods or in some cases, the car was left unlocked, he said.

Early Sunday, one victim caught a thief in his car in the 8900 block of West Rio Grande Avenue and detained the suspect until police arrived.

Numerous stolen items, along with marijuana, were recovered by officers.

Robert Morrison, 47, of Richland, was arrested and booked into the Benton County jail on suspicion of vehicle prowling, criminal trespassing, possessing stolen property and possessing marijuana.

Kennewick police volunteers, CHIPS (Citizens Helping in Police Services) have started their annual parking lot patrols to try to keep an eye out for thieves in parking lots and can call officers when they spot something suspicious.

But, Sgt. Lattin said, shoppers should remember to "lock it when you leave it" and keep valuable items out of sight in the trunk.
