5:30 PM ET: WWE Canada President Carl DeMarco calls Benoit's parents. His mother, Margaret home alone, answers. DeMarco says “I considered Chris one of my best friends…” only to get a response of “Why are you telling me this?” before realizing they hadn't been notified and saying he'd call back. DeMarco calls the detective in charge of the notifications, who called Benoit's mother. DeMarco then called Scott Zerr, an Edmonton report of friend of Chris who was helping with his autobiography, and told him to go to the parents' house and lend his support. Margaret calls her husband/Chris's father Michael and tells him to come home.
Around 6:00 PM ET: The deaths are reported on WWE.com.
6:05 PM ET: Dave Meltzer receives a call from a WWE source who tells him that Chris was the killer.
6:36 PM ET: Constable Rob Morris of the Royal Canadian Mounted Police was dispatched to the Benoit home. He assisted Emergency Medical Services in “a complaint of a distraught female [who] was just informed that her son, who lives in the United States, had passed away.” His report documents that he “called Detective TURNER to confirm details. Detective TURNER had already spoken with Chris’s Mother, Margaret BENOIT, and informed her of Chris’s passing. The incident was being investigated as an alleged murder-suicide.”
6:45 PM ET: Michael gets home. Zerr meets him in the driveway and tells him he was told by WWE that Chris killed Nancy and Daniel before killing himself.
Between 6:00 and 7:00 PM ET: Police tell a local reporter that Chris was the killer. The reporter mentioned this the next day on MSNBC.
Presumably some point before 8:00 PM ET: JBL asked Regal if he thought Chris had anything to do with killing Daniel right before Regal taped his tribute, rattling Regal (who knew that Chris had been losing it to some degree) enough to make sure he didn't praise Chris as a person. Chavo Guerrero, who (along with Scott Armstrong) got the text messages from Chris, tapes a tribute that goes overboard in talking about how he trusted his kids with Chris and makes it clear he knew what happened.
