BEND, Ore. -- Bend residents saw their second car break-ins spree of the week early Thursday, and two Bend RV dealers also were hit by thieves who stole pricey items from motor homes.

Nearly 10l cars along Long Creek Lane, Silver Lake Boulevard and Colonial Drive on Bend’s Westside were targeted, with some windows smashed. Others had been left unlocked.

Among the popular items taken: iPods, GPS systems and other electronics.

Police say it usually happens when kids are out of school, but there’s been a significant increase in recent days. Officer say they haven’t yet proven any connection between the latest incidents and those earlier in the week.

As for the RV break-ins, the first report came from Jerry’s RV early Tuesday morning, when workers called police to report several motor homes had been entered or had storage doors forced open. Officials say about $100 worth of cables and fittings were taken.

The second report came hours later from Larry’s RV off Highway 97. There, six trailers were entered.

Owner Larry Nonemaker said it isn’t the first time his place has been hit.

“I think it’s the third time in six months,” he said. “And they stole batteries … and I presume that’s used for drugs or something like that. And they broke inside, taking away flat-screen TVs or anything they could sell for money.”

Nonemaker estimated the latest losses at about $2,500.

Police said they don’t have any suspects yet, but since the break-ins are so similar, it’s likely they are connected.

A Prineville neighborhood was hit in the same fashion Wednesday, prompting police to issue familiar warnings about locking cars and keeping valuables out of sight.

Prineville police responded between 5:20 a.m. and 1:14 p.m. to five break-ins in the Ochoco Heights area, said Police Chief Eric Bush.

Items typically taken in such break-ins are anything of value that can be easily carried on foot and hidden, such as CDs, electronic devices, IDs and cash, Bush said.

Bush said at least three of the cars were unlocked, and no windows were broken.

Police are working several leads in the cases, but no suspects have been identified, Bush said.

He urged residents to keep vehicles locked and parked in well-lit areas, if possible. Valuable items should not be left in vehicles, Bush said, but at a minimum should be kept out of sight.

The police chief noted the challenges his agency faces in solving such "quality of life crimes, with the same number of officers as 1990, but twice the population and a larger geographic area to cover.

Meanwhile, a string of Bend car break-ins Monday night also has police looking for suspects.

Nearly a half-dozen cars on various streets around the city had windows smashed and pricy items stolen.

Several GPS systems, a rifle, fishing rod and electronic gear were stolen from cars on Portland Avenue, Wall Street and Beaumont Drive.

In the Old Mill District, a car parked at the Regal Old Mill Cinemas had three cell phones and a wallet taken.

Police said they don’t have any suspects and did not have enough evidence to say if the break-ins were related.
