Unfortunately it’s just a variation on a common theme. Turns out this guy is the ‘estranged husband of someone who may have been at the party’. I can’t fault a single woman for trying to get away from someone capable of this, and yet it is not that uncommon.
NYC just announced that the majority of women murdered there last year were victims of a ‘partner, parent, or some other relation’. I know a lot of male Freepers get upset with the sense that the law goes too far in issuing restraining orders against men in such situations, but to more deadly effect it often doesn’t go far enough.

And I'd bet money that two of the three dead victims turn out to be his estranged wife and her new boyfriend.
How would a restraining order stop this kind of madness?
Restraining orders only affect those not likely to do something like this. For this type only countervailing force will do it. But both LA and NYC "discourage" law abiding women, and men, from being prepared to apply that.
I suspect that is true in every city, or state. The incident of random murders is probably far lower than murder of someone that the murderer has had some time to develop hatred against.
Same can be said of many crimes of human on human. We do stuff to people we do not like more often than to someone we do not know.
