-the implication has been that he was stalking her.
If this was the case, that he was stalking her, this reminds me of that case in San Jose years ago where a co-worker was stalking a lady engineer who worked at a High tech company in the San Jose and ended up shooting her, She lived, and killing 7 others who worked with her.
I could have swore that anti stalking legislation got passed because of this, but would that have stopped this nut? I doubt it.
