Matthew de Grood will stay locked up in a secure psychiatric facility in Calgary for the next year.

He was found not criminally responsible for Calgary’s worse mass murder that occurred in a home in Brentwood in April 2014 where students had gathered for a party.

The victims in the attack were Kaitlin Perras, 23; Lawrence Hong, 27; Josh Hunter, 23; Zackariah Rathwell, 21; and Jordan Segura, 22.

de Grood spoke for the first time during a review hearing to determine his future.

This is the statement he read in court:

“I am deeply sorry and regretful that my illness led to this terrible tragedy. Five young people are no longer with us and their families are suffering immensely. For them I cannot express enough my regret and sorrow for their losses. No one deserves the pain I caused. That being said I will do everything in my power to ensure that my illness is safely managed so nothing like this ever occurs again.”

He said he’s deeply sorry his mental illness led to the stabbing deaths that killed Lawrence Hong, Zachariah Rathwell, Josh Turner, Katie Perras,  and Justin Segura.

de Grood told court he wants to get treatment.

The Alberta review Board has determined de Grood will stay at the Southern Alberta Forensic Psychiatry Centre for treatment and will come back before the panel in one year.
