Accused man discusses Canadian model murder

The popular Shanghai crime news show "Dongfang 110" aired footage Wednesday of 18-year-old Chen Jun describing the July murder of Diana O'Brien. The show is produced by Shanghai's police force and focuses on actual crime investigations.

The video that aired appeared to be from Chen's police interrogation.

Police contacted Friday had no further comment.

O'Brien, 22, had been in Shanghai for just two weeks on a short-term modeling contract when her body was found July 7 in a pool of blood in a stairwell of her apartment building.

Four days later, police announced they had arrested Chen in his nearby home province of Anhui carrying items from the apartment O'Brien shared with roommates. Police said Chen confessed to killing O'Brien.

The killing of a foreigner so close to next month's Beijing Olympic Games shocked a city that prides itself as being China's most modern.

In Chen's interview with police, he explained he was in O'Brien's apartment and was taking a laptop when O'Brien came out of another room.

"While I wasn't looking, she hit me and knocked me to the floor," Chen said.

He said he took out a knife and stabbed her. When she ran out of the apartment screaming, he said he stabbed her again in the stairwell, fearing the neighbors would come out to look.
