Calgary police have identified “several” suspects and are exploring new leads in their investigation into the homicides of four people in Calgary last month.
Cody Pfeiffer, along with sisters Glynnis Fox and Tiffany Ear were found dead in a burned-out car in Sage Hill on July 10.
Two days later, the registered owner of that car, Hanock Afowerk, was found dead in a traffic circle off Highway 22.
More than two suspects have been identified, Staff Sgt. Martin Schiavetta said Wednesday. He said those suspects won’t be identified until charges are laid in relation to the homicides.
Police believe Afowerk’s body had been dumped in the traffic circle at Highway 22 and Highway 8 some time before it was found.

Investigators are hoping to speak with anyone who saw suspicious activity while driving around the circle and then north on Highway 22 between midnight on July 10 and about 6 a.m. on July 12. In particular, police are hoping someone may have driven in the area in a vehicle equipped with a dashcam.
“Someone may have seen a body for example lying in a ditch. But also the absence of a body also helps with our investigative timeline,” Schiavetta said.
“What we’re trying to determine is when Mr. Afowerk’s body was actually dumped.”
Police are also asking anyone in the Moose Jaw, Sask. area to contact investigators if they find a “burn site” which may have a bag of discarded clothing — particularly shirts, pants and shoes — documents, or any other burnt materials.
It’s believed that bag could have been discarded near Canadian Forces Base Moose Jaw or the Moose Jaw Municipal Airfield.

Schiavetta said the investigation is “progressing very well,” and that police forces across the country have been very cooperative and helpful.
“We are of course processing hundreds and hundreds of hours of CCTV footage,” he said.
“This is an extremely complex, dynamic investigation and literally we are going across the country, picking up breadcrumbs of evidence, trying to corroborate that through video.”
Police had identified one person of interest in the investigation, 24-year-old Yu Chieh Liao, who goes by Diana Liao. Investigators said in July she has ties to Calgary, Vancouver, Moose Jaw, Regina and Toronto, and was last seen in Moose Jaw on July 12.
Police believe she and Afowerk knew each other, but didn’t elaborate on the nature of the relationship. It’s also believed Fox, Ear and Pfeiffer were wrapped up in a targeted attack against Afowerk, and were killed because they were in the “wrong place at the wrong time.”
She was arrested in Toronto on July 27 after a Canada-wide warrant was issued for fraud.
The man she is believed to have been travelling with, 25-year-old Tweodros Mutugeta Kebede, is in custody in Toronto after being arrested on unrelated drug charges.
