I didn't think People.com was even a news source.Mad Greek released a media statement that BK visit to Msd Greek is fake news
Either way it wouldn't have been necessary to stalk the victims in a restaurant or on SM if BK drove past that house 12 times. He could have decided that was the house he was going to target as early as August.
So far that is the only connection we know of that BK had to his victims. There is no evidence he ever had any contact with them until the night of the murders.
