In a chilling Facebook post, a B.C. man appears to have confessed to murdering his daughter, wife and sister.

At a press conference Friday, RCMP spokesperson Sgt. Stephanie Ashton said it was believed that “several members of one family, including the suspect, are deceased.”

Police are investigating two separate crime scenes, Ashton said. One scene is in Langley, B.C., and the other is at a Popkum, B.C., home where the suspect apparently lived.

In a Facebook post published Thursday night, a man named Randy Janzen appears to confess to shooting three of his family members.

He first seems to admit to killing his daughter, Emily, who apparently had suffered from years of chronic migraines.

“Over the last 10 days I have done some of the worst things I could have ever imagined a person doing,” the post reads. “I took a gun and shot her in the head and now she is migraine free and floating in the clouds on a sunny afternoon, her long beautiful brown hair flowing in the breeze, a true angel.”

Janzen goes on to apparently confess to killing his wife and sister.

“Then I shot Laurel because a mother should never have [to] hear the news her baby has died,” Janzen wrote. “Then a couple of days later my sister Shelly because I did not want her to have to live with this shame I have caused all alone.”

“Now my family is pain free and in heaven,” he continues. “I have great remorse and feel like the dirt that I am.”

Ashton said police were made aware of the incident just after 3 p.m. local time on Thursday, after Langley RCMP attained information “through social media” that indicated a man had harmed family members.

Police found a deceased individual in the Langley home.

RCMP also attended a second crime scene in Popkum approximately an hour east of Langley. Officers were apparently involved in a four-hour standoff at Janzen’s residence before the home caught fire.

Neighbours reported up to five gunshots during the incident, as well as what they described as “explosions.”

Ashton said police had used “less than lethal force” and set off “distraction devices” to attempt to gain access to the home.

Ashton said many details of the investigation -- including the names of the victims -- were still unconfirmed.

She said police were still unable to access the scorched house and were unable to confirm how many individuals were inside the home.

Ashton didn’t say why investigators were unable to enter the home, and gave no timeline into the homicide and fire investigations.
