You're right. Nothing about this makes any sense to us but I have no doubt the prosecutor has a motive in mind.
They said at the press conference that BC was not targeted. Could the referral have been from an online website listing? I don't know how Zillow and other similar sites like that work. (I worked in real estate but it was in the 2nd Dark Ages: pre-internet.) How do they determine which RE agent gets the referral from something like that? I had a throwaway email account I used when I was looking at homes for sale a few years back. I continued to receive email solicitations for similar properties from a particular agent and IIRC & AFAIK she wasn't the listing agent for any of the houses.
Gosh, everything has changed so much, it's crazy.
