Two men who were found in a car after they were stabbed to death have been named.
Police were called by paramedics to Montague Road, Leytonstone, north-east London, just before 1am yesterday.
Both men were pronounced dead at the scene.
The murder victims are Aaron Carriere, 21, and Josiah Manful, 20, who were both from east London, Scotland Yard said.
Post-mortem examinations found the cause of death for Mr Carriere was given as stab wounds to the neck, while the cause of death for Mr Manful was given as shock and haemorrhaging, and stab wounds to the chest.
No arrests have been made and an incident room has opened in Barking under Detective Chief Inspector Neil Attewell from the Homicide and Major Crime Command.
Forensic teams investigating the double murder inquiry yesterday combed a 200-yard stretch of Montague Road, scouring drains and gutters as they went.
A steady stream of mourners came to pay their respects and lay flowers at the police line.
A note attached to one bunch said: "rip aaron, always in our hearts, miss you. From jordan & mum xxx".
In tributes to the pair, local mourners identified the victims as "Josiah and Aaron".
A group of three men splashed the floral tributes with brandy before stopping to swap stories about the deceased.
In a written tribute another mourner said: "Nothing but love my brothers, may you rest in peace. Love Tony."
One resident said: "I left and when I came back I saw it. It's horrible and I just heard what happened. I am so sorry - it's terrible."
Police are appealing for anyone who witnessed the killings to come forward, by calling the incident room on 020 8345 3715 or Crimestoppers on 0800 555 111.
