Miles Sanderson, 32, was placed on parole in February while serving a sentence of more than four years, including assault and robbery. But he has been wanted by police since May, apparently for violating the terms of his release, although details were not immediately clear.
His lengthy criminal record also shows that he stabbed one of the victims killed in the weekend violence seven years ago, according to court documents.
Canadian Public Safety Minister Marco Mendicino said the parole board would investigate Sanderson’s assessment.
I want to know the reasons for the decision to release him, he said. I am deeply concerned about what happened in this case. A community has been shaken.”
Sanderson and his brother Damian, 30, are accused of killing 10 people and injuring 18 others in a series of knife attacks on an Indian reservation and in the neighboring town of Weldon. Damien was found dead on Monday and police are investigating whether his brother killed him.
Investigators have not yet given a reason for the attacks.
The Saskatchewan Coroners Service said nine of the dead were from the James Smith Cree Nation reservation: Thomas Burns, 23; Carol Burns, 46; Gregory Burns, 28; Lydia Gloria Burns, 61; Bonnie Burns, 48; Earl Burns, 66; Lana Head, 49; Christian Head, 54, and Robert Sanderson, 49. The second Weldon was from Wesley Patterson, 78.
Court documents say Sanderson attacked his in-laws, Earl Jones and Joyce Burns, in 2015, stabbing Earl multiple times and injuring Joyce. He later pleaded guilty to hitting and threatening to kill Earl Burns.
According to court documents, many of Sanderson’s crimes were committed while he was on drugs or intoxicated. She told her parole supervisor at one point that drug abuse was spiraling her out of control. Documents show that Sanderson repeatedly violated court orders prohibiting drinking and drug use.
