Matthew de Grood, Calgary stabbings suspect, set for court today

The man accused of fatally stabbing five young adults at a house party in Calgary a week ago is due for a court appearance this morning.

Matthew de Grood, 22, is being held at a secure psychiatric facility in the city’s northwest. It’s not clear if he will appear in court in person or via closed-circuit television.

He has been charged with five counts of first-degree murder in the deaths of Lawrence Hong, 27, Joshua Hunter, 23, Kaitlin Perras, 23, Zackariah Rathwell, 21, and ​Jordan Segura, 22. 

The five who died were at a house in Brentwood in northwest Calgary to celebrate the end of the university semester when they were stabbed to death at about 1:20 a.m. MT.

De Grood, the son of veteran Calgary police Insp. Douglas de Grood, was arrested a short time later a few blocks away with help from the K-9 unit.

Police have said de Grood knew at least one person at the party and was an invited guest. Investigators are examining text messages he may have sent in the hours leading up to the party.

Defence lawyer Allan Fey said it’s possible the Crown prosecutor will request a court-ordered psychological assessment.

Rathwell funeral on Tuesday

Also Tuesday, mourners will gather for the funeral of Rathwell.

The family extended a public invitation for people wanting to attend the service at the Centre Street Church in northeast Calgary at 1:30 p.m. MT.

Rathwell was in the band Zackariah and the Prophets, along with Hunter. The group had recently released its first EP.

The family has established the Zackariah James Rathwell Trust Fund to help students pursue their dreams in the arts. Donations can be made at any RBC location.

Funerals were held on Monday for Segura, Perras and Hunter. 

Hong’s funeral is set for Wednesday at the Centre Street Church at 1:30 p.m. MT.
