Do you have a source for that or are you guessing?
The story seems a bit dodgy, current husband saw the guy in his garden then ran inside the house, and rather than try to hold/lock the door and stop the attacker from getting in he seemingly left it open or unlocked resulting in his wife getting killed.
I read it on the local newspaper's website. Ilford Recorder.
I don't know why some people think the current husband is involved. It's not likely that he would team up with the ex to murder the mother of his children. No one can predict what they would do if they saw a man with a crossbow in the garden. He was running for his life.
