A teenager shot dead as he sat in a parked car is believed to have had no links to gangs, Scotland Yard has said.
Joseph Burke-Monerville, 19, was gunned down in Hindrey Road, Clapton, east London, on Saturday evening.
He was rushed to hospital but later died, while a 22-year-old man who was also in the car remains in a serious but stable condition, said police. A third man, aged 19, was also in the vehicle but escaped unhurt.
Terrified witnesses described how two men wearing bandanas walked into Hindrey Road at about 8.20pm when three gunshots were fired.
Mr Burke-Monerville, from the Islington area, died at about 11.10pm, police said. A post-mortem examination is due to take place on Monday.
Detective chief inspector Kenny McDonald, who is leading the inquiry, said: "Our early inquiries suggest that Joseph and those he was in the car with have no links to gangs. We continue to work to try and establish the motive for this murder.
"I would urge anyone who was in the area at the time of the shooting and may have seen the incident, or two males fleeing the scene, to contact officers."
Zach Carpenter, 18, saw two men wearing bandanas across their faces enter Hindrey Road. One of the men was black with a red and white chequered bandana, while the other man was white and was wearing a black bandana, he said.
Mr Carpenter said: "I was walking home from the shop when I saw a black man and a white man walking down the main road and turn into Hindrey Road. After about 30 seconds I heard three loud bangs. It's unnerved me a bit because my family live nearby."
Witnesses to the shooting or anyone with information about the incident are asked to call police on 101 or Crimestoppers on 0800 555 111.
