Lin, a native of China, was reported missing by an acquaintance on Tuesday — the same day the torso was discovered outside Magnotta’s apartment building.
He moved on May 1 into a downtown Montreal apartment, where the concierge said he knew him simply as Justin.
Alfredo Hedriana said Lin also lived with a roommate, who recently left for China for a vacation.
“He’s a good tenant, he’s a decent guy,” Hedriana said Friday.
“I heard that there was a body found, but I didn’t pay attention.
“But this morning, when I heard that it’s one of my tenants, I was shocked.”
Hedriana also said four of Lin’s friends — one woman and three men — came to the building looking for him two days before the torso was found.
Lin also kept a Facebook profile, which referred to him as Patrick Lin.
