Johan moved to Bruntal in the early 90s and began living with another couple who had the last name Liebert (not to be confused with the Lieberts from '86). The two had once had a son named Johan Liebert, but he died when he was a baby, so after a fire "accidentally" broke out where the town's birth certificate records were kept, Johan was able to jump into the dead boy's identity.

Johan provided the couple with a house in Offenbach Hessen, though he spent very little time at home and mostly used them as a means of backup to prove that he had a family or past if needed.

Julius Reichwein paid the couple a visit and warned them of what fate lay in store if they didn't run away from Johan as fast as they could. The two did not take his warning seriously and remained in their home.
