The most comprehensive criminal history record in Nebraska is the record maintained by the Nebraska State Patrol.
(Now here come the caveats)
This is a listing of arrests by any law enforcement agency in the State when the person arrested was fingerprinted, and the fingerprint card was submitted to the State Patrol.
This should include most arrests for felony crimes, and some arrests for misdemeanor crimes.
It would not include, however, many misdemeanor crimes for which the person was not fingerprinted.
Cases where the defendant was issued a citation and released after the arrest would be unlikely to appear.
It would also not include cases where the prosecutor filed the charge, and the defendant made a voluntary court appearance but was never arrested and fingerprinted.
So, all in all, there’s a lot to be missed using their records.
