How did this guy stab three men in his apartment all by himself?
With a high capacity, assault style knife?
I've been wondering that, too, since his ramming activities were around 9 or 9:30 pm -- lunchtime for the average adolescent; so they most likely weren't killed in their sleep, unless he did it the night before and "lived" with the bodies for half a day. It wasn't just the two roommates, but also their guest -- 3 on 1, and he was little. If he did it the same day, he must have had "help." So for now I'm thinking he offered them a spiked drink and when they passed out, he smote.
They were all foreigners, sent to the US for an education. Their poor parents.
Maybe he drugged his roommates before slaughtering them. He planned to slowly torture them while still alive. He also planned to take several ODs of pills AND shoot himself with 2 guns before the cops could close in on him after his rampage. He shot himself with at least one gun.
The media has been hush as to whether his roommates WERE merely stabbed or more viciously butchered and whether he had any drugs (prescription or otherwise) in his system/possession at the time of his death.
