While of course we can't rule out anything, I find the professional hit from another country theory highly unlikely, because of the staging and highly personal nature the crime appears to be. For instance, a real mob hit in NJ happened as follows: The target was lured out of his home at 9:30pm through a phone call. When he went to his car or his driveway, he was gunned down and left there. No staging, clear message, fast in and out. No staging, not killing his wife, etc. I find it unlikely that if the grudge was against Barry, Honey would have been hurt. No, this was someone who hated them both, and had something to gain only if they were both dead. Hmmm wonder who that could be?
