Even if they were buying drugs, which we have absolutely no reason to believe, a drug deal seems very highly unlikely after 2am, when he had to be up for work in 4 hours or less.Commenting on my own post, a robbery could happen at any time of day, but what other reason(s) would be likely for middle of the night? Someone else mentioned a drug deal? Jealously by someone who one of them was involved with? Owed money to someone and they were tired of the delay in paying?
Everything still points to it being targeted. The BIL had reason to believe so, police are guarding the family and there's been no community safety alert issued.
