Mentally Ill Man Seeks More Freedoms After Deadly 2014 Stabbing Rampage
13 Nov
Summary
- Calgary man deemed not criminally responsible for 2014 stabbing deaths
- Psychiatrist says he remains low risk to reoffend and is ready for more privileges
- Continues to suffer from PTSD and guilt/shame over his actions
In November 2025, a Calgary man deemed not criminally responsible for a deadly 2014 stabbing attack is seeking more freedoms. His treating psychiatrist, Dr. Sergio Santana, says the man, Matthew de Grood, remains a low risk to reoffend and is ready for relaxed rules to make it easier for him to visit his sister in British Columbia.
The request was made at an annual hearing before Alberta's Criminal Code Review Board, where Santana provided an update on de Grood's progress. Santana noted that de Grood continues to suffer from post-traumatic stress disorder (PTSD) and the guilt and shame over his actions, but said this indicates he wants to change and bodes well for his recovery.
In 2014, de Grood was charged with murder but found not criminally responsible due to mental illness. He was 22 years old at the time when he stabbed 5 people to death at a house party, believing he was attacking Medusas and werewolves for the son of God. The court heard he was suffering from schizophrenia during the attack.
