Firework may have started fatal blaze
Officers have warned the culprits they will be caught after confirming the fire started as a result of a firework attack on Thursday.
Mary Fox, 59, became trapped in the house in Carpenter Court, Bodmin, after pushing her teenage son to safety from an upstairs window.
The 17-year-old was taken to Treliske Hospital where he was treated for smoke inhalation and later released.
Speaking at a press conference at Bodmin police station, Superintendent Martin Orpe warned the people responsible for the firework attack that he was confident police would find them.
"As a result of a firework that was found late yesterday behind the door within the premises, and as a result of information from the public, this is being treated as a murder investigation," he said.
Officers leading the investigation said they would be looking at concerns that Mrs Fox's son, Raum, was being bullied at school.
Tributes have been paid to a schoolgirl who died after slipping in her high heels and falling under a train while waving goodbye to her friends.
