Peel police say human remains found in a Markham-area home may be the body of a Mississauga man who was reportedly kidnapped seven months ago.

Police have been searching for Jianguo Han since Jan. 20, when he was reported missing  from his home along with Xiu Jun Fei.

Investigators determined the pair had been kidnapped. Fei was found six days later, while Han's whereabouts remain a mystery.

On Tuesday, the investigation led police to a home in the Markham area where they found the remains.

Police won't confirm if the remains found at the house in Markham belong to Tony Han but are saying the investigation did lead them there.

"We have actually notified the family of Tony Han," Peel Police Const. Thomas Ruttan told CBC News. "Just in the event that it is related to this case."

Ruttan told CBC News a police dog was used to locate the remains.

"Once at the home, a cadaver dog did detect the presence of human remains and we are currently exhuming those remains," said Ruttan. "Once they’ve been exhumed, we will send them for forensic examination."

So far, four people have been charged with two counts of kidnapping with the intent to hold for ransom. An arrest warrant is outstanding for Guo Wei Wu, 43.

Han is a well-known realtor, dealing in high-end properties, particularly representing clients in the Mandarin-language community.

The case of his disappearance has received considerable attention in Toronto's Chinese media.
