Kuehnlein himself pleaded guilty of assault and stealing in two different cases, in 1988 and 1990. He successfully petitioned a judge in St. Louis County in 1998 to expunge his criminal record, which was making it hard for him to get work as a cop. The judge ordered those records sealed, as well as records of an acquittal for drunken driving and an assault arrest that did not result in charges.
