A 20-year-old man whose dead body was found inside a car in Ferguson after riots erupted had been intentionally set on fire.
St Louis County police identified the victim as DeAndre Joshua.
His death is being investigated as a homicide, but police have not said whether it is connected to the violence that broke out after the announcement of a grand jury decision not to indict white Ferguson police officer Darren Wilson in the fatal shooting of black 18-year-old Michael Brown.
Mr Joshua’s body was found on Tuesday morning at the wheel of a 2004 Pontiac parked near the apartment complex where Mr Brown was killed.
He had severe burns, and a post-mortem found that he had been shot once in the head.
