A registered sex offender from Wisconsin was arrested on attempted aggravated theft and identity theft charges Saturday night after trying to buy a vehicle with a fake Social Security number, name and address, Medford police said.

William David Fuchs, 44, is held in the Jackson County Jail in lieu of $30,000 bail.

Medford police Lt. Bob Hansen said Fuchs tried to purchase a $38,000 vehicle at a Rogue Valley car dealership, identifying himself as "Bill Fox," and also presenting the fake Social Security card and a fake address. The man later identified as Fuchs said he would return after the paperwork had been processed.

After finding out the Social Security number was a fake, the dealership contacted Medford police.

Police discovered Fuchs had contacted several local real estate agencies with the false premise he had inherited a lot of money and wanted to buy a high-dollar home. He also had asked jewelry store clerks to put pieces on hold and told them he intended to buy the jewelry with an inheritance.

"Really no crime there," Hansen said. "(But) it inconveniences the store."

Hansen said he believes Fuchs' actions stem from a fantasy of being wealthy and able to purchase high-value items.

"He likes to portray himself as having lots of money and just goes out and gets these things," Hansen said.

In addition to being a registered sex offender, Fuchs also was convicted of fraud, but police officials could not confirm whether the conviction also happened in Wisconsin.
