Mr Musgrove was the manager of Coney Hall Football Club
A football manager who was shot dead on a playing field suffered wounds to the heart, kidneys and spleen, a post-mortem examination has found.
Ryan Musgrove, 36, was shot at least six times at the Sparrows Den Playing Fields in West Wickham, Bromley, south London, by a man who fled on a bicycle.
Mr Musgrove had arrived for training at Coney Hall Football Club when he was targeted by a man hiding in bushes.
Detectives have said Thursday's shooting could be gang-related.
Police said the victim was talking to two men at the side of the field when he was attacked. Police suspect the killer may have been lying in wait.
Det Ch Insp John McFarlane said: "Suddenly a man jumped out of the bushes, fired several shots with a small handgun, then rode away on a mountain bike across the adjacent field in the direction of New Addington."

The gunman fired again to scare away the dying manager's players before fleeing, police said.
Mr Musgrove, from South Norwood, south-east London, was not known to police.
The club said in a statement: "The thoughts of everyone within the club are with Ryan's family to whom we send our heartfelt condolences.
"Ryan will be remembered as a huge personality and as a great football man who made great strides improving the senior section at Coney Hall during the past two seasons.
"He is missed."
The gunman was described as being aged between 19 and 30 and quite tall.
He wore a hat covering the whole of his head, large goggles and a white mask over the bottom half of his face, hiding his ethnicity.
No arrests have been made.
