That’s a pretty old dodge, it happens a lot. When caught doing something, perps commonly claim that somebody would kill them if they didn’t carry out what they did. Even if true, he murdered 5 people to save himself? Why not just go to the cops? If he actually is in the military, there’s a thousand people that he could’ve talked to about this (chaplain, first sergeant, etc.) not to mention he could get a room in the barracks and stay on base to stay away from whoever is threatening him. He could even request that the cops meet him at his house when he’s picking up personal effects to take back to the barracks. This guy is either a liar or a complete moron, probably both.
Sounds like he went to the cops a couple of months ago and got tossed in the loony bin for his trouble.
