Police are alleging a 22-year-old man killed his mother, aunt and uncle in Monday’s triple homicide in Etobicoke.

On Wednesday, police identified the victims as Tatiana Khalilova, 49, of Toronto, Svetlana Babaega, 76, of Russia, and Victor Zybin, 76, of Russia.

Their bodies were found at a townhouse on Old Burnhamthorpe Road near Renforth Drive on Monday evening.

The suspect, Alexander Khalilov, has been charged with three counts of second-degree murder.

Police received a 911 call shortly before 7 p.m. on Monday, after a family member discovered the bodies and notified police, Insp. Tim Crone said.

The bodies of the three victims were removed from the townhouse just after 3 a.m. on Tuesday.

Police said the suspect was apprehended "in the area."

"He was armed,” Crone told reporters at the scene Monday evening. "We negotiated with the suspect over a short period of time and he subsequently surrendered."

Witness Mike Bettencourt said the suspect was carrying a knife and was arrested after a brief standoff in a nearby ravine.

"The fellow was in the ravine with a seven-inch knife and the police had the opportunity to jump him and they arrested him," Bettencourt told CTV Toronto.

Other residents were shocked by the news of the deaths.

"It’s a big tragedy and a big loss for the neighbourhood because they were really, super-nice people," one female resident said.

Autopsies have been scheduled to determine the causes of death, but police say the victims suffered blunt force trauma.

Neighbour Mellisa Uzelac said people were shocked when they learned of the triple homicide.

"Oh I’m shocked. Nothing like this has ever happened around here," Uzelac said. "So I was really shaken up."

Anyone with any information about this case is asked to call police at 416-808-7400, or contact Crime Stoppers anonymously at 416-222-TIPS (8477).

Also, a family friend has set up a trust fund to help Khalilova's daughter, Julia. Donations can be made at any Royal Bank branch, transit number 06802, account number 5020532.
