What do you do when your only murder witness saw the whole thing via webcam? A boyfriend living in China witnessed the murder of his girlfriend, Qian Liu (“Necole”), in Toronto over the internet.

Liu, a 23-year-old from Beijing attending York University, was found dead just before noon last Friday in her apartment. Police in Toronto are still looking for the man her boyfriend saw struggling with her in the wee hours of Friday morning.

According to police, Liu was engaged in an online chat with her boyfriend via webcam at around 1 a.m. when an unknown man knocked on her apartment door.

“She opened the door to a male. She could have known the male but he was unknown to the online witness,” Toronto Police Det. Frank Skubic said.

Shockingly, it took responding officers over 10 hours to arrive at the scene after Liu’s boyfriend reached her friends living in Toronto.

Toronto Police Constable Tony Vella says they weren’t notified of the crime until Friday morning.

“Someone had gone to (her) address because they were concerned for her well-being and they went into the apartment and they found her there and they were concerned so they contacted police,” he said.

When her body was found, Liu was naked from the waist down, but there weren’t any signs of sexual assault.

“She was unclothed from the waist down and had been dead for a period of time. There was no trauma to the body which could readily identify the manner of her death and no obvious signs of sexual abuse,” Skubic said.

Police say that Liu’s laptop is also missing.

York University President and Vice-Chancellor Mamdouh Shoukri said the university’s “deepest condolences and heartfelt sympathy went go out to Liu’s family, friends and classmates.”

“Qian’s death is a terrible tragedy and our entire community mourns the loss of a promising young student,” he added.

York University spokesperson Susan Webb says they are concerned for students who live off-campus.

“We’re doing everything possible to make this a safe environment. It can be a challenge when we don’t have any authority off campus,” Webb said.

There are currently no suspects in custody.
