TORONTO — The estranged boyfriend of a woman whose body parts were found scattered around Toronto has been arrested and charged in connection with her murder, police said Monday.

Chun Qi Jiang, a 40-year old construction worker, appeared in court on a second-degree murder charge in the killing of Liu Guanghua, a single mother of three. He will appear again in court Sept. 10.

Police Insp. George Koekkoek said both the victim and suspect are Canadian citizens of Chinese descent. The couple dated for four years and recently broke up.

Liu's head, foot and hands were discovered in a river west of Toronto earlier this month. A few days later, her two calves, a thigh and an arm were found in a creek in eastern Toronto.

The 41-year-old was last seen alive Aug. 10 when she was dropped off by friends at the spa she owned.

Court documents show the suspect lived near a townhouse where Liu lived with her eldest son. According to police, her two younger children live with their father.

The case received extra attention following the case earlier this year of porn actor Luka Magnotta, who is accused of dismembering a Chinese student in Montreal and mailing his body parts to political parties and a school. Police have ruled out any connection between the cases.

Police still do not know how Liu died. Parts of Liu's body have yet to be recovered.
