Believe it...I went to the service of my friend David. There's more to it than what the papers are printing. Still under investigation. He just wanted to get his kids. No reason to shoot an unarmed man.
Evidently, from perusing on-line news articles from back in June, there is in fact more to the story.
Apparently the assailant had a history of violence against his [former] wife when they were still married. TRO denied because she couldn't commit to the follow-up hearing due to new job, so she went for the divorce.
Dumb move to keep the same locks, knowing he still had (or likely had) keys after having lived there, given the prior violent behavior.
Possibly avoidable situation with new locks, but ultimately it's probable that his continued assertion of his "right" to control his former wife's life would have led to a bad outcome of one sort or another.
People who compulsively control others will often ignore restraining orders, and everyone "is shocked" that an official piece of paper failed to function effectively as a magic talisman.
I'm guessing that, short of picking up and moving out of the area, there would be little the newly married couple could do to avoid a violent confrontation.
This was never going to end well.
