Police are investigating several calls which came in following the 20th anniversary appeal into the brutal murder of an Aylesbury bookie.
John Sheppard, 63, was stabbed to death as he worked at John Horwood bookmakers in Cambridge Street on the evening of Saturday December 3, 1994.
Despite a high-profile appeal and thorough investigation at the time, John’s killer has never been found.
Now 20 years on, police have reopened the cold case in a bid to gather fresh information.
Since the appeal on December 3, police say they have received several calls which they are following up.
A spokesman for Thames Valley Police said: “Regarding the John Sheppard case, we have had some calls which we are following up.
“However, we would still urge people to make contact with us if they have any information about the case – particularly the identity of the offender.”
If you have any information that could help the investigation, please contact the major crime investigation review team on 101.
The police are offering a £10,000 reward for information which leads to the conviction of the offender.
Crimestoppers is offering a separate reward of up to £10,000 to anyone providing information which leads to the conviction of the person or people responsible for his death.
