A man accused of committing a mass stabbing in Canada reportedly took pills moments before he died.
Police say Myles Sanderson, 30, and his older brother Damien Sanderson, 31, killed 10 people and wounded 18 others in a horrific rampage on an indigenous reserve and a nearby village in Canada's Saskatchewan province on September 4.
Myles became in "medical distress" shortly after being taken into custody at the end of a four-day manhunt, and was pronounced dead at hospital.
The Saskatchewan Coroners Service have since announced two public inquests into the tragedy, one into the stabbings and the other into Myles' death.
Speaking to local reporters, chief coroner Clive Weighill said they had "found no blunt force trauma" on the suspect.
A number of sources from government, police, and healthcare have since told CBC News that Myles had taken took some form of drug just before he died following a pursuit on a highway.
Officials are now awaiting toxicology and neuro pathology reports before determining the cause of Myles' death, which could take up to four months to arrive.
At a press conference on Wednesday Mr Weighill also confirmed there would be no criminal proceedings taking place due to both suspects having died, saying: "With the suspect deceased, there will not be a public criminal trial."
"Without a public hearing of the facts, it will leave many questions unanswered from the families involved and the public pertaining to the circumstances leading to the deaths,"
The inquest meanwhile can not be held until the investigation has been completed, and is expected in late spring or early summer 2023.
Myles' brother Damien also died on September 5, with separate enquiries ongoing into the circumstances of his death.
