Scott takes Hooch to the police precinct the next day, where a wedding occurs just across the street. Hooch recognizes the wedding photographer as Amos' killer and gives chase. The murderer is able to escape from his pursuers, but Scott is able to identify the killer as Zack Gregory, a former Marine with several prior arrests who also fits the profile of Amos' killing (Scott had earlier speculated that Amos' murderer must have had special experience in killing as the stab wound performed on Amos ensured total discretion). Scott also speculates that Amos wasn't murdered in a robbery attempt, but in order for Zack to cover up an illegal operation near to where he lived. This theory matches with Amos' regular complaints to Scott about the noises he heard going on at Boyett Seafood, the company that has Zack registered as an employee.
