Florida authorities say a Toronto couple found dead in their Hallandale Beach home in January were asphyxiated, and police are looking for at least two suspects involved in the homicide.
Hallandale Beach Police Chief Dwayne Flournoy also announced in a Wednesday press conference a $51,000 reward for information leading to an arrest in the deaths of Rochelle Wise, 66, and her husband, David Pichosky, 71.
Flournoy said the medical examiner has concluded the couple "died due to asphyxiation," but he would not specify exactly how that occurred.
"The other thing we know from the crime scene, and the science of the crime scene, is that this was not perpetrated by a sole perpetrator," he told reporters at a Hallandale Beach news conference.
"There were multiple culprits in this double homicide. And as we release more details of this homicide, you will find how senseless this murder is."
Detectives have not identified a motive, he added.
The bodies of Wise, a popular former day camp director and educator, and Pichosky were found on Jan. 10 in their winter home in Hallandale Beach.
Wise and Pichosky were scheduled to meet neighbours for lunch, and when they didn't hear from the couple, the concerned neighbours used a spare key to check the home and found the couple inside.
Last month, police released video from a neighbour's surveillance camera hoping to identify a woman seen walking to the rear of the couple's home on Jan. 9.
