The man who killed a senior couple from Alberta nearly a decade ago has been denied day parole.On Thursday, a parole board in Abbotsford, BC decided not to grant Travis Vader access to the outside world, telling him, "your risk to the public would be undue at this point in your sentence." He was sentenced to life in prison in 2017 after being found guilty on two counts of manslaughter for the deaths of Lyle and Marie McCann.Also present at the hearing was the McCanns' son, Brett. "Our pain is everlasting. I will never forget, or forgive, what Vader has done," he said. "Vader did not testify in his trial, and he denied any involvement in several press interviews over the years prior to his conviction. He, in fact, continually insulted their memory by his conduct towards our family."McCann said it was "critical for Vader's rehabilitation that he admit to having committed the murder of my parents," and "provide authorities with the location of my parent’s remains.""It is very important to myself, and my family, that my parents’ remains be located and buried properly," he emphasized.The incident took place on July 3, 2010 as the couple were headed on a road trip to British Columbia. Their charred motorhome was discovered days later near Edson, Alberta, near the BC border, though no bodies were ever recovered.
