Someone forced their way into the Recycling Center in early March and stole two large sacks of aluminum cans, the executive director of the not-for-profit said.

Insa Riepen, the executive director of Recycle Utah, said the aluminum cans disappeared sometime between 4:30 p.m. on Sunday, March 3 and 8 a.m. the next day. She said a chain-link fence on the east side of the Woodbine Way property had been cut, allowing the person or people inside. She said the damage to the fence was "not immediately apparent."

The sacks are made of heavy duty mesh plastic, she said. They were filled with the aluminum cans, and each of the sacks weighed at least 100 pounds, Riepen said.

She declined to disclose the dollar value of the loss but said the aluminum cans were valuable. The theft is a "slap in our faces," Riepen said.

"It's insulting. It's hurtful. It's a big downer for staff," she said.

Riepen suspects the person who stole the aluminum cans will sell them to a metal yard. Nothing else was taken. Riepen said metal products have been stolen from the Recycling Center before, but she said the case in early March was the first involving someone forcing their way into the premises.

"Metal at the moment is worth money," she said.

Rick Ryan, a Park City Police Department captain, said the investigation is continuing. He said the police contacted major recycling firms in the Salt Lake Valley seeking information about whether large sacks of aluminum cans had been sold to them. None had, he said. Ryan acknowledged that investigators had few leads. Footprints were found, but Ryan said many of them were made by Recycle Utah employees.

Thieves occasionally target the Recycling Center, which collects a variety of recyclable products. The Recycling Center in the summer of 2011 suffered a string of break-ins over the course of one week.

In the 2011 cases wiring was taken from the grounds and a small amount of cash was stolen. Recycle Utah said at the time the wiring was taken from appliances stored at the site and other places on the grounds. The wiring could be sold on the black market, Riepen said at the time.

Anybody with information about the case may contact the Police Department at 615-5500 or the department's anonymous-tip line, 615-5847. The department also has an online tip form. The direct link is: https://www.tipsubmit.com/WebTips.aspx?AgencyID=994.
