Should I confront a co worker who followed me home one night and wanted to fight me?

So this happened last year around Christmas time that 3 co workers followed me home one night. One was because the manager lied to one of them saying I was flirting with his girlfriend. The second one is a guy who made a death threat towards me it wasn’t that serious after all about him because it turns out he has a mental disorder. And so does the other guy who is clinically insane and quit working because of it and the 3rd guy was the tag a long with them. So it’s been bugging me lately because it took me time to put the pieces together and after hearing from a neighbor they knocked on his door looking for me. I now it’s the truth I couldn’t say for sure at the time because I didn’t see them but has heard their voices as I live up stairs but after talking to my neighbor and from over hearing their conversations the night they came to my house. It’s the truth. Should I confront the 3rd guy as he is a manager at my work and the other 2 have left?
