Toronto police arrested 29 year-old Brian Dickson yesterday and charged him with first degree murder in the death of York University student Qian Liu, 23. Liu was attacked at around 1 a.m. last Friday as she videochatted with her boyfriend, 6,000 miles away, in Beijing. Despite her boyfriend's frantic attempts to contact her friends in Toronto, Liu's body was only found by her landlord ten hours later, stripped from the waist down, but showing no sign of sexual assault or obvious trauma.

The Toronto Star reports that Dickson may have once been roommates with Liu. [NYDN, Image via AP]
