Torso in suitcase belongs to Guang Hua Liu

A human torso found in a suitcase floating on Lake Ontario belongs to Guang Hua Liu, the Toronto woman whose body parts were found in Mississauga and Toronto last month, police have confirmed.

A pair of boaters found a suitcase floating in the water a couple of kilometres off shore Wednesday morning and towed it to Bluffer's Park — located in the city's east end. Once ashore, they called Toronto police.

Liu's former boyfriend, Chun Qi Jiang, has been arrested and charged with second-degree murder. Peel Regional Police are heading the investigation into Liu's killing and evidence from Wednesday's discovery has now been turned over to them.

Liu was reported missing on Aug. 11, one day after friends dropped her off in front of a now-defunct spa she owned called the Forget Me Not Health Centre in east Toronto.

On Aug. 15, her right foot was found in the Credit River in Mississauga, Ont., about 45 kilometres west of her home.

Liu's head and hands were later discovered in the same river in the Hewick Meadows Park area. Days later, two calves, a thigh and an arm were found in West Highland Creek, just blocks from where she lived.

Forensic tests determined all the remains belonged to Liu.
