The mother of three B.C. children murdered by their father is living in fear since learning he'll be able to apply for escorted day trips in the community, a family member says.

Allan Schoenborn was found not criminally responsible last year for killing his children, 10-year-old Kaitlynne, eight-year-old Max and five-year-old Cordon, three years ago. Last week, the B.C. Review Board ruled that he'll be allowed to apply for supervised day passes from the Forensic Psychiatric Hospital in Port Coquitlam.

His ex-wife Darcie Clark is terrified by the decision, according to her cousin Stacie Galt, who has taken Clark into her Coquitlam home.

"I'm concerned for my cousin Darcie, I'm concerned for myself, my own well-being," Galt told CTV News. "I'm scared. I'm scared for her whole family, her mother who lives in Merritt.... We're scared that if he does get out on this day pass he will escape."

She says she's also worried about the safety of people who live in the area of the hospital.

"He's not fit to be in this community. He's not fit to be around children, to be around people. He should be in jail, where he belongs," Galt said.

Family lawyer Kathleen Walker says she can't believe that Schoenborn could be allowed into the community, and she's encouraging people to contact the government.

"There is a sense of, where is the justice? Three little children have had their whole futures, their lives taken away from them in a most horrific, catastrophic kind of way," she said, adding that the decision should be appealed.

Federal Conservative candidate James Moore says people in the Tri-Cities have been calling his office, demanding to know how this decision was allowed to be made.

"They should reverse it and they should give their heads a shake, because common sense has clearly escaped their sense of judgment," he said.

"I don't care if he's sedated, I don't care if he's surrounded by corrections officers, it's just wrong."

B.C. Attorney General Barry Penner says that once he receives a copy of the review board's reasons, Crown lawyers will have 15 days to launch an appeal.

"I will be looking closely at those written decisions to see if we have a good chance of appealing this case," Penner said.

"It's worth noting Mr. Schoenborn has not been released, he has not been granted any temporary escorted absence at this point. That will be up to the psychiatrist to determine."
