The man who died at a pool party event organised by a Jamaican reggae star in a Surrey mansion has been named as 34-year-old Ricardo Hunter.
A post-mortem revealed Mr Hunter died from a single gunshot wound during the private event.
Police and ambulance crews were called to the property in Church Lane, Headley, shortly after 2.30am on Monday morning as screaming revellers fled the scene.
Mirror Online understands a number of gunshots were fired and pictures from inside the party show how the property was packed with around 500 guests

A 38-year-old man from London arrested on suspicion of murder remains in custody while a 30-year-old woman from London arrested on suspicion of assisting an offender has been bailed until September.
DCI Paul Rymarz, from the Surrey and Sussex Major Crime Team, said: “This was a shocking incident where a man lost his life and we are determined to bring those responsible to justice.
“This incident has understandably sent shockwaves through the Headley community and we are working with our Safer Neighbourhood Team colleagues to update and reassure residents.
Aerial pictures showed a forensics tent in the back garden of the luxury property amid the scattered remains of litter and debris from the event.
He said: "It's a huge event and there were security guards and everything outside. At around 2.30am I was woken up by the noise and went outside to see loads of people outside the property.
"Then suddenly all these brand new Land Rovers and sports cars all started racing away. The police and ambulances arrived a few minutes later.
"You could see people coming from the house covered in those foil blankets and obviously extremely distressed. I saw one girl in particular in complete shock.
"It was bedlam there were police everywhere, armed officers, a helicopter overhead, the whole village is in complete shock this morning."
Another neighbour told Mirror Online residents had complained about the annual event which was being held for the third time.
He said: "It's an annual party which happens in this house between the pub and the vicarage.
"There's loud aggressive rap music, people doing donuts in the fields in their Range Rovers, people just batten down the hatches when it's on."
