Two Waterloo men are now facing manslaughter charges in connection with the kidnapping of a Markham real estate agent in January.

Senthuran Sabesan, 23, and Sohiab Malik, 21, appeared in a Brampton court on Thursday, along with 23-year-old Gobinath Shanthkumar of Newmarket who also faces a manslaughter charge.

The defence lawyer for Sabesan, Daniel Brown, says "The police haven't told me anything other than the fact that my client is charged with manslaughter."

Sabesan was one of four people charged in January with kidnapping with the intent to hold for ransom and is also charged with aggravated assault in the case. A fifth suspect is still being sought on similar charges.

The manslaughter charges come after human remains were found by cadaver dogs encased in concrete in the basement of a Markham home.

Although the remains have not yet been officially identified, they are believed to be those of real estate agent Jianguo (Tony) Han.

On January 20, Peel police were called to a Mississauga mansion on Featherston Drive where two men were reported missing.

Xiu Jun (Johnny) Fei, the owner of the house for sale, and Han, the realtor selling the house, had both disappeared from the $2.4-million home.

An investigation concluded that the two men had been kidnapped. Fei was located six days later injured but alive, but the search for Han has continued. His family has been told to brace for bad news.

Sabesan and Malik were both remanded in custody and are scheduled to appear in court again next week. Charges could then be upgraded again.
