I hope this isn't too far off topic but something similar did happen in a case I worked.
I was a fairly new patrolman & was sent to a call where a man said he'd been threatened.
I talked to the victim who explained he had another guys wife in his home, she wanted him more than her husband. I spoke with her & she was there of her own free choice.
The victim said the husband was really ticked (no kidding) and has a handgun.
I told the victim if the hubby showed up don't answer the door, don't confront him, call police immediately & we'd handle it.
I said "for all I know the hubby could be hiding in the bushes".
HE WAS! it was night, the house was surrounded by thick unkept shrubs.
(getto-hood) Sure nuff, soon as I drove off the hubby appears, knocks on the front door, the "victim" asnwers, opens the door armed with a hatchet.
The hubby promptly shoots the victim in the throat with a .22 revolver.
The victim survived. Hubby goes to jail. Woman runs off with someone else.
Don't bring a hatchet to a gun fight.
