Investigators are asking the public for help in answering questions about a very public murder-suicide that occurred last weekend.

Calgary Police revealed on Tuesday, following an autopsy, that the victim of the Saturday, April 15, homicide was 69-year-old Joanne Suk-Wah Tse.

Police confirmed that Tse had her hands and feet bound before being thrown from a Spruce Place SW condominium building, next to the Shaganappi Golf Course and Bow Trail SW.

“I want to express our condolences to the family and friends in the residence of Spruce Cliff who have been deeply impacted by the tragic events over this past weekend,” said Calgary Police Homicide Unit Staff Sergeant Sean Gregson.

He said that the circumstances behind the crime are unknown and that the homicide itself was unusual for Calgary.

“This is a very unique event. I can’t remember 24 years of being a police officer that I’ve seen something like this.”

Police seeking whereabouts of 2023 Subaru Outback

SSgt. Gregson said that police are looking for the location, and for the person who currently has the perpetrator’s white 2023 Subaru Outback SUV. That vehicle’s licence plate is CNR0008.

The service took the unusual step in identifying the perpetrator as 61-year-old De Lin Tang, after he committed suicide following the homicide.

Tang took his life by also jumping from the condominium as first responders were attending to Tse.

The Calgary Police Service has been providing, and will continue to provide victims services to anyone who saw or was affected by the incident. Victims Services support can be reached by calling 403-428-8398.

“If there’s more people out there that need some supports, we’re there to help,” said SSgt. Gregson.

He said that as the investigation has progressed, they noticed that his vehicle was missing from both the crime scene and from Tang’s residence.

“It just leaves a question: Well, where is it? How did he get there? maybe somebody that has that vehicle can answer some of those questions for us.”

He said that those questions are also being sought by the immediate families of Tse and Tang.

Anyone with information is asked to call police at 403-266-1234, or submit tips anonymously to Crime Stoppers.
