The dad of murdered student Meredith Kercher has died after a suspected hit-and-run.
John Kercher, 77, was found with a broken arm and leg after the accident on Windmill Road in Croydon, south London, on January 13.
He had no memory of what had happened and was taken to a south London hospital for treatment but died from his injuries on Saturday.
A neighbour, who asked not to be named, said: "He was across the road in the shop. He came out. It was quite misty that day.
"All of a sudden people came out of the shop and he was on the floor."
Detective Sergeant Steve Andrews, of the Met’s South Area Command Unit, said: “We are currently treating the death of this man as unexplained and our thoughts are with his family at this very sad time.
“Despite thorough enquiries made so far, including speaking to witnesses and examining potential CCTV opportunities, we’ve not as yet been able to establish how the man came to sustain his injuries which included a broken arm and broken leg.
“We are keeping an open mind as to the circumstances of his death, including whether he may have been involved in a collision.
“Please make the call to us, or anonymously via Crimestoppers if you can help us determine what happened.”
The Met Police would not comment further when approached by Daily Star Online.

John is survived by sons John, 43, Lyle, 40, and daughter Stephanie, 36.
He split from Meredith’s mum Arline more than 20 years ago.
According to The Sun, his family have said in a statement: “We loved him dearly and he is going to be very sorely missed.”
John’s youngest daughter Meredith was murdered on an exchange trip in 2007 at the age of 21 in Perugia, Italy.
Her American housemate Amanda Knox and Knox's Italian boyfriend Raffaele Sollecito were convicted of murder but later cleared on appeal.
Rudy Guede, a drifter, was jailed for 16 years for murder and sexual assault.
John worked as a national newspaper journalist for 40 years.
He spent years at The Sun and the Daily Mirror and was friends with its former editor Piers Morgan.
A tireless campaigner for justice in the case of his daughter's death, he later wrote of his family's anguish that the spotlight had focussed on Amanda Knox.
He said he was writing a book about Meredith to introduce the world to his "beautiful, intelligent and caring" daughter.
John wrote: "I also hope this book might help to keep Meredith's case in the spotlight, and, in some small way, to keep alive the hope that we might yet know the truth about her death."
