Following the discovery of the shotgun that killed Edward Simpson in 2019, homicide detectives are reissuing an appeal for information that will bring his family justice.
Detective Chief Inspector Katherine Goodwin, who is the Senior Investigating Officer into the death of Edward Simpson, said: "Since 2019, Edward's family have not had justice for his death and although we have recovered the weapon that fatally killed him, we still need more evidence to bring his killers to justice.
"Someone out there will have information about why Edward was killed and by whom. I need anyone who might know about Edward's death to contact my team so we can look into it and try and build a case to convict his killers.”
An investigation was launched after police were called to Exeter House on Watermill Way at 23:08hrs on Friday, 21 June 2019 to reports of a shooting.
Armed police, local officers, London’s Air Ambulance and the London Ambulance Service attended and found a man injured.
Despite the efforts of paramedics, a 25-year-old man died at the scene a short time later. The victim was identified as Edward Simpson of Laleham, in the borough of Spelthorne, Surrey.
A special post-mortem examination took place at Fulham Mortuary on 23 June 2019 and gave the provisional cause of death as a single gunshot wound to the upper body.
The weapon used to kill Edward was recovered by police investigating the supply of firearms by Cristobal Ngomo. It was recovered on 25 June 2019 by surveillance officers watching Ngomo and associates for offences unrelated to this murder.
Forensic analysis confirmed that the weapon seized on 25 June 2019 was the weapon that killed Edward. It was a prohibited pump action 12 bore shotgun.
At the start of the investigation, five people aged between 22 and 34 years old were arrested on suspicion of murder, on suspicion of harbouring an offender and on suspicion of conspiracy to commit murder.
Four have been released under investigation and one with no further action.
Officers are working on the hypothesis that Edward was not the intended target, but was caught in the middle of a feud between two rival drug dealers.
DCI Goodwin, added: “Finding the gun is one step towards building a case to convict the shooter and anyone else involved in helping the suspects remain undetected all this time.
"Edward's family remain distraught that the killer took such a loved member of their family and has not been put before the Courts to stand trial. I really implore for anyone with any information to think about the grief and daily sadness that Edward's mum has to go through."
In a statement, Edward's mum and sister, said: "Once again, we are pleading to anyone with any information about Edward’s murder to come forward and speak to the police. We would be so grateful for even the slightest bit of information that can help the police catch Edward's killer."
