My thoughts are similar but involve more of a "rendezvous" with someone who just got off work at the last stop bar. After reading the YELP review of the DH (if true) written by a patron who states he was unknowingly drugged, no memory after 3 drinks and later his GF saw 2 scary guys dump him at his house all bruised & cut. Didn't remember a thing till he woke up the next morning and found $2000 charged on his account.... I could easily see TD drugged (could explain what was going on with him when they got to the hotel) arrangements made to meet alone (but not really alone) and something nefarious happening from there. If the friend new he may have been trying to shield BD from it by offering to look for TD, saw the beginnings of the hook up and decided to leave. Also, the friend may have told LE everything he knew from that night and it checked out. LE may have told him to stay quiet to protect the investigation. JMO & tossing thoughts around.
