Funerals for Calgary stabbing victims under way

Friends and family of three of the young people stabbed to death at a house party in Calgary last week are gathering to say goodbye today.

The service for Jordan Segura, 22, began at 10 a.m. MT Monday morning at the funeral home where he worked part-time. A tree will be planted in his memory at Fish Creek Park. 

Mourners are also attending separate services today for Kaitlin Perras, 23, and Joshua Hunter, also 23.

Perras's funeral will be held at 1 p.m. MT at First Alliance Church in southeast Calgary and attendees are encouraged to wear colourful attire. In lieu of sending flowers, her family is asking for donations to a dance scholarship established in her name. 

The funeral of Joshua Hunter takes place at 2 p.m. MT.

A funeral will be held Tuesday for ZackariahRathwell, 21, and on Wednesday for the fifth victim, Lawrence Hong, 27.

It's alleged Matthew de Grood, the son of Calgary police Insp. Douglas de Grood, stabbed the five students at an end of university classes gathering in the northwest community of Brentwood around 1:20 a.m. MT last Tuesday before fleeing.

He was apprehended shortly after by police with help from the K-9 unit, and has been charged with five counts of first-degree murder.

He is scheduled to make a court appearance on Tuesday in Calgary.

De Grood's lawyer, Allan Fay, said he is not aware of any mental-health concerns with his client, and that de Grood has not been placed on suicide watch.

A court-ordered psychological assessment has not yet taken place, but Fay said he understands the Crown prosecutor may request one at de Grood's court appearance on Tuesday.
