Lost horror movie from 80s maybe early 90s

[kevster6981]

Hi, I've been trying to find a rare horror movie I saw a long time ago but I can only remember the beginning. 2 murder scenes. The first murder scene happens when a woman gets kicked out of a cab and while she is picking up her purse she is attacked by a humanoid of some sort.But the next morning she is found hanging from a bridge and a tourist boat collides with her from under. The second murder scene is a homeless guy crying for help who gets dragged in the river by his feet.  I know it's not much but I can only remember these 2 scenes. It's similar to split second 1992 or predator 2 but I still can't find it. I came across c.h.u.d but it wasn't that either. If you might know the title of this movie it would be appreciated.

Thanks
