When I was FAR too young to watch such a thing (mid- to late 80s), my parents allowed me to watch this movie where a woman keeps accidentally appearing to have murdered people. Like, she’ll stumble into a body, fall over and land with her hand on the knife. I think it was played for laughs… some sort of dark comedy? I remember chalk outlines featuring prominently. I did watch it on TV (probably a VHS video), but I’m pretty sure it was a movie. I’m curious why my parents let me watch it! Anyone have a guess as to what this movie was? I remember the part above and one scene where a bloodied man is banging on doors in an apartment building and ends up dying in her doorway… before he dies, someone hands him a wallet, thinking he is the bad guy and is trying to rob them (and of course it does him no good). Again, she looks very guilty of a series of murders, but the audience can see that she totally didn’t do it. I think she is on the run from the police for this reason, which makes her look MORE guilty.

Not an exact match but your description made me think of “Foul Play”.
