But it has been found by a 30-year-old dental student who tracked her down and returned it.
Eric Wherley says he found the wallet in a bathroom stall at school after a water pipe broke and loosened some ceiling tiles. The thief who stole the wallet apparently had hidden it in the drop ceiling.
The dark-blue patent leather wallet contained Baumberger's driver's license, library cards and Social Security card. It also had her student ID, a grocery list, and cloth swatches from her bridesmaids' dresses.
Baumberger says she and her husband are planning to give Wherley a gift for his efforts.
