An autopsy has confirmed the human remains found in a Markham home on Tuesday are those of missing real estate agent Tony (Jianguo) Han, police say.

Han and Johnny (Xin Jun) Fei were kidnapped from a Mississauga mansion on Jan. 20. Fei was found safely six days later.

On Thursday, police charged three men with manslaughter. They and a fourth man are also accused of aggravated assault and two counts of kidnapping with the intent to hold for ransom.

Peel police revealed on Friday they are also looking for a 43-year-old man they say drove the getaway car, a red minivan. Wei Guo Wu is Asian, 5 feet 7 inches tall and 170 pounds with black hair and brown eyes.
