Police said two men, Jianguo Han and Xiu Jun Fei, were kidnapped. Fei was found shortly after.

The identity of the remains is still unknown and police said they are still looking for Han.

Senthuran Sabesan, 23, from Waterloo, was arrested in January and charged with two counts of kidnapping with the intent to hold for ransom.

Hinthurjin Baskaran, 21, from Toronto, was arrested in June and charged with two counts of kidnapping with the intent to hold for ransom and two adults, who cannot be named due to a publication ban, are charged with two counts of kidnapping with the intent to hold for ransom.

Wu is described as Asian, 5'7" tall, weighing 170 lbs. with black hair and brown eyes.
