Joseph Burke-Monerville, 19, was shot dead in a suspected case of mistaken identity in Clapton on 16 February 2013.
The teenager, a forensic science student at the London Metropolitan University, was sitting in a parked car with two of his brothers in Hindrey Road.
At around 8.20pm a gunman approached the car with a second suspect before opening fire.
Joseph was hit in the head and died at 11.20pm after being airlifted to hospital. His older brother David, 33, was shot in the arm. Joseph’s twin brother Jonathon, 20, was unharmed.
Three men were charged with murder but the case was dropped in May 2015. An inquest heard evidence the shooting was part of a feud between the Amhurst Road (A-Road) gang and rivals from the Pembury estate.

Yassin Omar Mohammed, 28, died at a care home on 14 May 2013, four years after he was left paralysed from the neck down as the result of being hit over the head with a bottle.
He had been attacked in Greenhill Road, Wembley, as he made his way home from a party at around 3am on 1 April 2009. A special postmortem found the cause of his death was bronchial pneumonia linked to the spinal injuries he suffered during the assault. Prior to his death, police charged a man with GBH but the suspect was acquitted.
Surjeet Singh, 23, was stabbed in the neck during a brawl at a fairground in Southall Park, Southall, on 26 August, 2013.
His killer has never been identified. Seven men were charged with conspiracy to commit GBH but they were all acquitted after a trial at Isleworth Crown Court in April 2014.
The body of Damian Chlywka, aged around 30, was found in a well in the garden of 11a Audley Drive, Warlingham, Croydon, on 15 November 2013.
He had last been seen alive in March 2011.
A postmortem revealed he had suffered multiple broken bones. In 2015 an inquest recorded a verdict of unlawful killing.
Antonio Rodney-Cole, 22, was stabbed to death in Stoke Newington at around 11.30am on 2 December 2013.
Detectives believe he was attacked during a robbery of the mobile phone he used to deal drugs to customers in the area.
He managed to drive a short distance up Marton Road before collapsing. He was pronounced dead on arrival at hospital as a result of a stab wound to the leg.
Five men were arrested during the investigation but nobody was charged. The inquest in 2020 heard a suspect had been identified but had fled the UK.
Rowan Thomas-Williams, 20, was shot dead after spending the evening celebrating a friend’s birthday on 6 December 2013.
Detectives believe he was attacked near an address in Mulberry Court in Neasden, northwest London, at around 1.30am, when residents reported hearing gunshots. Rowan was taken to hospital by friends but it did not have an accident and emergency department and an ambulance had to be called. Police were alerted about his injuries just before 2am. He was pronounced dead at 9.40am and a postmortem confirmed the cause of death as gunshot wound to the chest.
Rowan’s mother Ruth Thomas said in a statement: “Rowan’s loss is not only felt by me, but also his father, his children and his younger sisters. Rowan was only a young man when his life was taken. Rowan had his whole life ahead of him. He was at the age where he wanted to build a future for himself and his children.”
