Edit: Not a honeypot but a confidential source. The killer or did they intercept his browsing session?
If "engineer" was actually so high up that they were a public figure that might be something, but Christopher Pence is no such houshold name.
His former employer was utterly irrelevant.
Here are some examples of relevance:
He never wanted to leave MS and victim is who he blames for having to leave.
He hates MS now and victim is someone important in MS.
He has a fortune in MS stock and victim is about to do something that will tank that stock.
He is Steve Ballmer. Reason doesn't matter, Ballmer is notable all by himself.
And what about his current employer (or occupation whatever that may be), why a former employer?
