Forensic investigators are collecting evidence at the home of a suspect in the grisly dismemberment murder of Hua Guang Liu on Tuesday.

Police crews and a forensic team continued to search the Scarborough townhouse of Chun Qi Jiang, one day after announcing the victim’s estranged boyfriend had been charged with second-degree murder.

Investigators were also sweeping an underground garage connected to Jiang’s townhouse, located on Brimwood Boulevard, near Brimley Road and Finch Avenue.

Jiang, 40, appeared in a Brampton court Monday on charges of second-degree murder of Liu, whose body parts were discovered in two Toronto-area parks in recent weeks.

Peel Regional Police Insp. George Koekkoek said Jiang, a construction labourer, was Liu’s recently estranged boyfriend who had arrived in Canada from China in 2002.

It is believed that Liu had been dating Jiang for four years before her death. Police could not say when the couple broke up.

Police said Jiang was identified as a suspect early on in their investigation. At one point, they searched a Scarborough motel room because a man by the same name had checked in around the time of Liu’s death.

CTV Toronto’s John Musselman reports that forensic officers planned to complete their investigation later Tuesday.

Neighbours previously told CTV Toronto that the resident of the townhouse unit was seen washing tools last week in the backyard, while wearing gloves.

“My mom, she said she saw him outside, cleaning stuff with his hands and she said he was wearing rubber gloves,” said neighbour Malek Mustapha Abdullah.

The investigation shocked neighbours, who said Jiang was a quiet man who they seldom saw or spoke with.

“It’s insane. It’s a very quiet, good neighbourhood,” said resident Shannon Leynes.

Liu, a spa owner and mother of three, was reported missing in early August and confirmed deceased after her partial remains were discovered along the Credit River in Mississauga’s Hewick Meadows Park two weeks ago.

Additional body parts, including an arm and a thigh, were found in an east-end Toronto park the following week.

The two locations are about 50 kilometres apart.

Some of Liu’s body parts are still missing and police still don’t know how she died.

Investigators are still trying to determine where the murder took place.
