Custom Made Killer

S3, E12: Michael and K.I.T.T. are after a loan shark who sends his deadly driver out to kill those who might stand in his way. Two people have been killed and when a third murder happens, Devon makes a connection between them. The man behind this is D.G. Grebbs who hires muscle men to go around "cleaning" his money. He is a loan shark who has his hands in the garment industry, "helping" designers who have little or no cash but good ideas.
