A fetus found outside a midtown Toronto apartment building is not connected to the murder-suicide of a Canadian Forces veteran and his newlywed wife that happened at the same address earlier this week, police have confirmed.

Police said remains that appeared to be that of a human fetus were found close to a recycling bin on Wednesday morning, shortly after 9 a.m. The remains were discovered by a resident outside of 111 Raglan Ave., in the area of Bathurst Street and St. Clair Avenue West.

Homicide detectives and the coroner's office were called to investigate.

Officers were also called to the building at approximately 6 p.m. on Sunday, when it was reported that a couple had fallen to their deaths from the building's 21st floor in what police are calling a murder-suicide.

They were identified as Canadian Forces Sgt. Robert Giblin and his wife Precious Charbonneau.

Investigators said they believe Charbonneau was pregnant at the time. She had been stabbed multiple times prior to falling to her death, officers said.

Police initially said that they didn’t believe the remains are connected to the other case. On Wednesday afternoon, investigators confirmed that the two incidents were separate.

Police are canvassing the neighbourhood for witnesses and information. They are concerned a woman may need medical attention.

Investigators aren’t sure how long the remains were in the parking lot. An autopsy on the fetus will be conducted tomorrow.

Anyone with information is asked to contact them at 416-808-7400 or through Crime Stoppers anonymously at 416-222-8477 (TIPS).
