Who Killed Theresa?

How we know Régis Lachance was a police informant - #18 WKT6

Synopsis

I desperately wanted the informant to be Luc Gregoire, the Sherbrooke sexual predator I was convinced had not only murdered my sister, Theresa, but may have been responsible for the murder of Louse Camirand and the death of Manon Dubé, so I emailed Jean-Pierre and asked him to respond with the name. This was all very dramatic, and he gave me the impression he was minutes away from retrieving it. Not able to wait, I blurted out, "Gregoire" in an email message. Rancourt responded, "Non, I will find it... His name is Regis Lachance"For more information please visit the website: theresaallore.com
