You made it up.
I could just as easily say that Martin was being stalked by a stranger in a car while on the way home (true). He ran away and lost the guy (true). After a minute he started home again only to be confronted by the guy who was now looking for him on foot and who had a gun.
The stalking stranger with the gun accosted him. Martin defended himself and over-powered the stranger with the gun who had followed and stalked him.
