A federal judge sentenced a Davis property manager to four years and three months in prison on Thursday for stealing the identities of multiple tenants and using their information to open new bank accounts under their names. He faced access device fraud and aggravated identity theft charges.

The United States Postal Inspection Service, the federal law enforcement agency charged with policing the nation’s mail system, headed the investigation.

William R. Stanley Jr., 31, worked as a property manager at the Tuscany Villas Apartments in Davis, where he lived for a year beginning Feb. 17, 2015, according to a U.S. Department of Justice news release. He also worked at three other apartment complexes managed by the same company.

Stanley used a fraudulent driver’s license that bore his photograph but the information of a different person, according to the news release. The tenants, as well as the property company, knew Stanley only by his alias.

Stanley used his managerial position to gather personal information about tenants, and from prospective tenants who filled out rental applications. Stanley would then access their financial accounts or open new accounts using their name, listing himself as an authorized user.

The Department of Justice said Stanley also stole the wallet of an 82-year-old man who left it in a grocery store, and used the man’s information to open new lines of credit that named him as an authorized user.

Stanley’ actions have cost his victims about $24,400, according to the news release. Stanley will have to pay restitution in addition to serving his sentence, though the amount has not yet been determined by the court.

Assistant United States attorneys Matthew Segal and Owen Roth prosecuted the case, which was handled by U.S. District Judge Morrison England Jr.
