Bill Weckerle is the patriarch of the Weckerle family, who were the victims of armed robbery in the first and second episodes of season 1, 21 Jump Street (episode). He made an additional appearance in the fifteenth episode of season 2, I'm Okay, You Need Work.
He witnesses, how Tyrell Thompson terrorises his son for his own reasons to the extend that he breaks into his apartment and threatens him and his family with a gun in the name of collecting money Kenny owes to him.
Later, after Tyrell is in jail, he sends his son, who has a drug problem, to a private center. There he is mistreated and dies because of it. His death haunts him since then, because he didn't listen about what was going on there until it was too late.
