For the GTA: San Andreas Serial Killer, see Mr. Trenchcoat
This ped can be found in Portland Island, mostly in the industrial areas like Trenton. He wears a fedora, a long trench coat or jacket and boots. He is called the Serial Killer because he looks very much like a similar ped in GTA San Andreas who is also rumored to be a serial killer.
Players have reported that the serial killer ped would attack them unprovoked and with no warning at all. Some players reported that the ped spawns with weapons as well. After investigating the weapons part of the myth, he does not spawn with guns unless you do a cheat. The serial killer ped has been investigated thoroughly, and nothing out of the ordinary was discovered about him. The pedestrian exists, but it is proven that he is, in fact, not a serial killer.
