The deaths of a mother and son killed in a Boxing Day fire in Tottenham have been ruled homicides.
Nottawasaga OPP confirmed on Thursday that the deaths of 48-year-old Adrienne Nesich and her nine-year-old son, Matteo, were not related to the fire.
No other details have been released by police about cause of death.
Nesich's other son, Jaiden, was not home at the time of the fire.
Nottawasaga OPP were called to conduct a wellness check at a home on Pyne Hills Court in New Tecumseth shortly after 5:40 p.m., Dec. 26, at which point they requested the assistance of New Tecumseth Fire Rescue and Emergency Services.
Two people were found dead inside the home; a third person was taken to hospital and later pronounced dead.
The other person identified as deceased is Christopher Nesich, 45.
OPP Const. Cindy Jacome said this is an isolated incident and police have no additional information to release at this time.
A pair of GoFundMe pages, started by family members to raise money for Nesich's older son, have raised nearly $75,000 combined. Some of the funds from one of the accounts will also be donated to the Canadian Mental Health Association (CMHA).
