Horror on Greyhound 1170

Yesterday the Globe and Mail, along with a number of other new sources, reported on a horrific encounter on a Greyhound charter bus in Manitoba.
"He put his bags in the overhead compartment. He didn't say a word to anybody. he seemed totally normal," said Garnet Caton, a passenger on bus 1170, in an interview with the Globe and Mail.
According to the Globe and Mail, Caton served five years in the Canadian Forces and was the closest to the attacker at the time of the murder.
the suspect was relieved to be 40 year-old Vince Weiguang Li. He was charged with second-degree murder yesterday. The National Post reports he may have been going though marital problems at the time.
The man was described by Caton as being "totally normal" and waring sunglasses.
"About a half hour later (from the time Li sat down on the bus), we heard a blood-curdling scream and turned around and the guy (Li) was standing up, stabbing this guy repeatedly," said Caton.
The Globe and Mail reports that the victim was Tim MacLean, a young aboriginal man, no older than 20 years-old.
All the witnesses claim there was no confrontation of any kind between the suspect and victim. The Globe and Mail reports that the victim even offered the suspect his seat when they both arrived on the bus.
The victim was stabbed "40-50 times in the neck and in the chest area", Caton told the Globe and Mail.
"When he was attacking him, he was calm as like, it was like he was at the beach. He (was) totally calm, he didn't say anything. There was no rage or, or anything. He was just like a robot stabbing the guy," Caton told the Globe and Mail.
After the initial attack the driver pulled over and opened the door to let everyone else escape. But this was only the beginning.
A trucker stopped nearby to see what was going on.
"Everybody got off the bus. But a few of us, me and the trucker and one of the Greyhound drivers went back on the bus to go see what was going on and that's when we saw," Caton paused, "he (Li) had the guy (MacLean) on the ground, he was cutting his head off and pretty much gutting him."
According to the Globe and Mail, Caton, the trucker and the Greyhound driver attempted to keep the killer on the bus with tools from the trucker's truck, like crowbars and hammers. Caton told the Globe and Mail they kept him on the bus by holding their bodies against the doors.
"He went back and brought the head to the front and pretty much, you know, displayed it (MacLean's head) to us like that and then dropped it on the ground in front of us. Very calmly, all very calmly, he was wearing sunglasses and like, you know, it was no big deal to him," said Caton.
The National Post reported that Judge Rocky Pollack order Li to be held in custody until he speaks to a lawyer, pending a court ordered psychological evaluation.
