The case was put over while Puffer undergoes a 30-day psychiatric assessment.

"I definitely think it's appropriate to have an assessment done," said duty counsel lawyer Bob Haslam.

Powers and Lee were found Thursday morning stabbed to death inside their southwest Braeside home.   

The accused is Lee’s son, who was living with the couple, police said.

In a statement released to the media, the Puffer family asked for privacy as they try to cope with the killings.

"We share the grief of the Powers family and send them our condolences as we mourn this tragedy together," the family said.

"Our sorrow is combined with concern for our son and brother, Derek. We hope that he will now receive the treatment he needs and we will stand with him as he goes through that painful process."

Couple remembered

Powers retired in October 2009 after almost 50 years in the sports broadcasting and communications business.

The couple met at a fundraising event in Calgary and married in 1989.

"The two were a perfect pair — Billy loved to tell jokes, and Donna Lee loved to laugh," read their obituary.  

"They enjoyed a wonderful life filled with love and laughter, a wide circle of friends and their most precious grandchildren and great-grandson."

A celebration of life is planned for the week of July 15.

Their family says condolences can be forwarded through the website of McInnis and Holloway Funeral Homes, and memorial donations can be made directly to the Association for the Rehabilitation of the Brain Injured or to the Canadian Mental Health Association.

A tree will be planted at Fish Creek Provincial Park in the couple's memory.
