Authorities are trying to find out how two large computer servers belonging to the D.C. tax office ended up in a trash alcove behind a restaurant.

A building maintenance man found the 3-foot-high servers behind a Ruby Tuesday in Columbia Heights early Wednesday. The servers are labeled "Property of D.C. Office of Tax and Revenue."

Officials haven't yet determined whether the servers contain any personal information about the city's taxpayers, they said.

Federal investigators want to see if the servers contain any evidence related to a multimillion-dollar embezzlement case in which two former tax office employees have been charged.
