Three thefts were reported Monday at the Student Recreation Complex, edging the number of reported larcenies in the building to 15 in 2012.

In 2011, there were 48 reports of larceny, MU Police Department Capt. Brian Weimer said.

The rising number of reported thefts has catalyzed additional signage to warn students against leaving possessions unattended. Signs also profile areas, such as the Jungle Gym and the basketball courts, as high-risk for theft.

“It’s a pretty high area for larceny for the campus,” Weimer said. “There are a lot of people who go there. People need to lock their stuff up. They can’t just leave it lying around.”

Stolen items range from apparel to cash and electronic devices. Carelessness on the part of the owner is often the root of the theft.

“Some of our students don’t recognize the fact that leaving valuable items unsecured is a problem,” said Diane Dahlmann, Student Recreation Complex Services and Facilities director. “The thefts that have occurred have been the sort of situation where somebody would leave their iPhone in plain view and walk off for a game of basketball. It’s items of perceived value being left in open places, which other students take advantage of.”

Freshman Caitlin Foli learned the lesson firsthand. Foli’s pink Patagonia jacket and student ID card were stolen from a cubby in the Jungle Gym in January. After using a treadmill for approximately 45 minutes, she returned to find them missing.

“I never thought my belongings would have been stolen, especially since they have the cubbies in an open area,” Foli said. “After having my things taken, I have been more cautious about what I wear to the gym. If it is something that I think may be risky to leave out, I will either bring it with me or lock it in a locker.”

Foli filed an incident report with MUPD and her possessions were returned two weeks later after a suspect was identified.

“They were able to see (the girl) take my jacket and rewind (a camera) back to when she scanned into the rec,” Foli said. “Once they matched the time she scanned in to her ID number, they were able to figure out who she was.”

Cameras are often used to track down thieves, but they aren’t 100 percent effective.

Students are encouraged to avoid the situation altogether and utilize the lockers outside of the Jungle Gym, which requires a refundable quarter, or to bring a lock for a larger space in the locker room.

“You cannot leave stuff lying around even for a moment,” Weimer said. “If you think you’re on the basketball court standing right there and you will see someone take your belonging, that is not always the case. Secure the items. When you use a locker, put a lock on it.”
