A federal investigation of a prosthetic devices manager at the University of Minnesota Medical Center is examining whether he duped patients into replacing their prosthetic limbs — and sold them on eBay, the Star Tribune reported.

The manager, Peter Stasica Jr., was placed on paid administrative leave about two weeks ago, a hospital spokesperson said.

The spokesperson said that the hospital is cooperating with local and federal authorities in an ongoing investigation. Stasica has not been replaced and the length of his suspension from work has not been defined. The program continues to serve patients. 

The hospital, owned by Fairview Health Services, normally donates available prosthetics to charity. The Star Tribune reported that the FBI traced at least 21 prosthetic limbs or parts to Stasica’s eBay account in the last six months.

Stasica is currently the secretary for the Minnesota Society of Orthotists, Prosthetists and Pedorthists, whose mission is “maintaining and elevating the standards, education and ethical conduct of…professionals,” according to its web site.
