Calgary police say they still don’t know the exact motive for the killings of three people found dead in two homes in the city earlier this week.
The body of Taylor Toller, believed to be the girlfriend of the man accused in all three deaths, was found in a home in the 2000 block of Applevillage Court S.E. on Tuesday.
A short while later, the bodies of Shawn Boshuck, the accused’s mother, and Alan Pennylegion, the accused’s stepfather, were found at a home in the 10100 block of Hidden Valley Drive N.W.
Police believe Pennylegion and Boshuck died as the result of an assault early Tuesday morning.
Calgary police Staff Sgt. Martin Schiavetta said investigators believe Toller was killed days before her body was found, likely in the early morning hours of Thursday, July 26.
As police work to piece together an exact timeline, investigators are looking for information from anyone who may have been in contact or been with Toller between July 26 and July 31.
Schiavetta said officers have been canvassing the area and collecting CCTV footage which is helping them to narrow down the timeline. He added police had been called to the Applewood home in the past for unrelated matters.
“I think it goes without saying that this is certainly one of the most tragic events that a family can ever go through,” Schiavetta said. “It took a lot of courage for the family to be here today as well as family friends.
“I can also say that this file, the scenes, have certainly taken a toll on our investigators, as well, that are processing it. You can imagine this was a very traumatic incident and certainly processing those scenes would be really challenging for the investigators and anyone involved.”
The cause of death for the three victims are not being released out of respect for the families, police said, adding that the case is considered to be domestic in nature considering the relationships between the victims.
Dustin Duthie, 25, was arrested on Tuesday and has been charged with three counts of second-degree murder. He remains in custody awaiting his next court appearance scheduled for Aug. 8.
Shane Graham, a close family friend of Pennylegion and Boshuck, spoke on behalf of the families. He was joined by two of the couple’s sons, David and Adam.
“The family has been torn apart by the actions of Dustin William James Duthie this week,” Graham said. “It is nothing short of a tragedy that has many ripple effects and has affected many people in different areas. We are hopeful that justice will be served and are so thankful for the support that everyone has given us in the past two days.”

He went on to say that the past two days have been an “incredibly difficult time,” adding that some family members — including two of the couple’s children — have not been able to make it to Calgary yet.
He went on to ask for privacy for the grieving families, adding that if anyone would like to offer financial support to Pennylegion and Boshuck’s children, they can do so through two GoFundMe accounts that have been set up.
Global News has learned Duthie was taken to the Rockyview General Hospital and was admitted under the mental health act following his arrest.
Calgary police are expected to give an update on the investigation at 5:30 p.m. MT on Thursday. Global News will stream the update live.
