Whoever did it had an accomplice. Or he had a gun. I think, if TT, despite his boxing prowess, without a gun, hard to kill individually. BM was an MMA person. They weren't little trusting, frightened nurses like the eight Speck took over, promising he wouldn't hurt them.
I also wonder how no trace evidence left at scene and why BMs + his crew's circle of acquaintances not questioned more thoroughly, and if DNA/fingerprints present, theirs not tested against it.
Say the pizzeria order is on the level--meal for one, sure not for three pot-smoking guys.
Effects of pot would not have incapacitated them. But mentioned here,maybe one at a time killed as they came home. Laborious dragging bodies about all by oneself? Even a big man would find it time-consuming.
I don't want to cop bash, as they do a heck of a job,many many dogged detectives, but think they had a theory and fit the investigation to it. Still, should have...FBI should have....should have, would have...
