A Frederiksen Court community adviser has resigned after being arrested and charged with multiple counts of burglary in the Frederiksen Court area.

According to an ISU Police press release, David Breitwisch, 22, formerly of 4214 Frederiksen Court, used master keys to gain unauthorized entry into several apartments between Jan. 2 and Jan. 14.

Breitwisch, senior in computer engineering, entered and stole materials from four or five apartments, said Capt. Gene Deisinger of the ISU Police.

A resident of Frederiksen Court reported to ISU Police Jan. 14 that he and his roommate had returned to their apartment and found Breitwisch, their community adviser, inside the apartment without their knowledge or permission, according to the release.

Breitwisch had not taken anything, but some DVDs were moved and stacked on the floor, the residents said.

ISU Police executed a search warrant Jan. 15 at Breitwisch’s apartment and recovered items that resembled possessions residents had reported missing. The recovered property included DVDs, backpacks, calculators and MP3 players, according to the release.

ISU Police arrested Breitwisch Tuesday and charged him with one count of second-degree burglary, a Class C felony, and three counts of third-degree burglary, a Class D felony.

Breitwisch was a community adviser for a cluster of apartments in Frederiksen Court. Each adviser has master keys for every building in his or her cluster.

“It’s a great responsibility [to have master keys],” said John Shertzer, residence life coordinator.

Shertzer said each community adviser goes through an interview, reference check and training before working at Frederiksen Court. On-call advisers have keys to apartments in case of emergencies, lockouts and maintenance checks.

“Once we found out that Dave was accused [of theft], he submitted his resignation,” Shertzer said. “Students maintain a trust level with staff members and we hope they don’t lose that.”

In an e-mail to Frederiksen Court residents, Mary Beth Golemo, apartment community director, said the “keying-in” policy has been revised. The new policy states that community advisers are not allowed to enter a room alone and must give residence 24 hours notice before entering, except in emergencies.
