Murder of Guylaine Potvin: the suspect led a solitary life in Granby


Marc-André Grenon seemed to be living a lonely life in Granby, as his arrest for the murder of Guylaine Potvin on Wednesday caused consternation in his neighborhood.

“You don't expect to see this anywhere near you, usually it's just business on TV or in movies. It's not reassuring, let's say, “testified Sylvain Boyer, who lives in the same duplex as the alleged murderer.

Investigators and crime scene technicians remained a good part of the day Wednesday in the apartment of the 47-year-old man located on rue Laval Sud, in Granby, in search of evidence.

“He was a loner. I saw him take a walk from time to time, but I didn't talk to him,” said a woman who has lived in her apartment for 18 years.

“He seemed like a fairly quiet person to me. and no problem. I didn't get to know him very well,” said his upstairs neighbor.

Severed ties with his family
