U.S. District Judge Joseph Bataillon sentenced Kevin L. Cave on Friday to probation and fined him $8,000.
The 37-year-old Cave, of Bellevue, pleaded guilty in August to selling information from the Nebraska Criminal Justice Information System database to auto dealerships that wanted to find and repossess vehicles.
Cave pleaded guilty to one count of exceeding authorized access to a protected computer for private financial gain.
Prosecutors say he sold the information about 60 times between March 2010 and August 2012 and was paid $200 for each lead resulting in a repossession.
Cave worked at Omaha police from 2002 until September 2012.
