A teenage university student who died after he was gunned down in an apparently random attack was described as a young man whose "smile will charm the angels".
19 year old Joseph Burke-Monerville was in a parked car when he was shot in Hindrey Road, Clapton, east London, on Saturday evening.
Mr Burke-Monerville, who according to his Facebook page was studying forensic science at the London Metropolitan University, had no links to gangs, police believe.
He was rushed to hospital but died later. A 22-year-old man who was also in the car remains in a serious but stable condition, while a third man, aged 19, was also in the vehicle but escaped unhurt.
