MEDFORD — Thieves targeted two construction sites over the weekend, stealing tools and equipment from contractors' trailers, Medford police said.

On Sunday morning, workers discovered trailers had been broken into at the Sportsman's Warehouse construction site at the Delta Center near the intersection of Crater Lake Highway and Delta Waters Road, Medford police Lt. Tim Doney said. Padlocks were cut, and drills, saws and other power tools were reported missing from the trailers, which belonged to contractors and subcontractors on the project, he said.

Workers also found fishing reels scattered around the site, indicating that the thieves also had broken into cargo containers holding store inventory, Doney said. A full list of the sporting goods taken wasn't available yet.

On Monday morning, crews returning to work at the U.S. Cellular Community Park, a sports field complex across town on South Pacific Highway, found trailers belonging to electrical and landscape contractors had been broken into, as had LTM Inc. equipment.

"We are entertaining the idea that they could be related," Doney said of the two similar crimes.

He said criminals likely will trade the tools and equipment on the streets, possibly for drugs. However, the missing tools are the livelihood of the contractors hit in the thefts, he noted.

To help investigators in case of theft, people should keep track of serial numbers of tools and other property and consider etching an identifier on tools, Doney said.

The cases are being featured on Crime Stoppers, which offers a reward for information that leads to a conviction, so anyone who saw anything suspicious at either work site or knows of someone who suddenly has lots of tools can call 800-3-DETECT (800-333-8328).
