Police have launched homicide investigations into the deaths of a 52-year-old Canadian woman and a 36-year-old American man in Belize after a post-mortem examination revealed that both had died from strangulation.

Autopsies were performed on the couple Tuesday morning, Belizeā€™s Corozal Police Department confirmed to Ā鶹“«Ć½.

Francesca Matus and Drew De Voursney were reported missing after they were last seen leaving a local bar in Corozal, Belize on April 25.

After nearly a week of searching, Matusā€™ white SUV was discovered on Sunday in a sugarcane field near the village of Paraiso, located approximately 15 kilometres away from the bar. Police say the coupleā€™s bodies were found together a day later in an ā€œadvanced state of decompositionā€ by a search party in a sugarcane field in Chan Chen Village, in the countryā€™s northern Corozal District.

Police say both Matus and De Voursney had tape around their wrists then they were found. They believe that murders are a case of a robbery gone wrong.

Matus leaves behind twin 22-year-old sons.

Jackie Logan, a friend of Matusā€™, told CTV Toronto that Matus owned a beachfront property in Belize

ā€œShe spent this past winter there and then she was due to come back and she didn't make it on the plane,ā€ Logan said in an emotional interview with CTV Toronto. ā€œShe deserves so much better than this. She really does.ā€

On a rainy Tuesday, friends and neighbours stopped by Matusā€™ Keswick, Ont. home to lay flowers in front of the house. Many expressed shock and disbelief.

ā€œThis is just a horrible situation,ā€ neighbour Tony Tallon told CTV Toronto. ā€œJust horrible.ā€

Neighbour Ryah Lopizzo described Matus as ā€œa good friendā€ and ā€œa great neighbour.ā€

ā€œIt's just a complete shock that she had to go through this.ā€
