1980s TV suspense movie in a large city involving a deranged killer (female?).

One scene is where the hero is out at night on the city streets, having just left a bar, and thinks he hears someone in the dark.  He trails after whom he thinks might be a deranged  killer that has been in the news.  The streets are dark and there  is construction scaffolding and canvas up over the sidewalks with colored lights illuminating them.  He finally gives up trailing and at that point possibly calls the police.   The movie’s ending climax is where the heroine enters her apartment building, rides up to her floor and goes into her apartment.  Minutes later, the killer (woman?) with a weird wig and disguise bursts in and begins to attack the heroine with knife.  The hero, having followed heroine to apartment, then enters and eventually shoots the killer dead, saving the heroine.  Having been previously notified, the police finally arrive as the movie ends.

    1. Thanks for your reply. I watched the clip and Murphy’s Law is not the movie. I don’t think it was a Charles Bronson movie. Let me know if you have any other ideas.

Got something to say?
