A reward of up to £5,000 is being offered for information on the murder of night club boss David “Les” Ross.
Mr Ross, 39, was found dead in the Village Express Hotel in The Jamb, Corby, on December 17 following an assault.
He died as a result of a blow to the head, and was found in his room at around 2.40pm.
Crimestoppers is offering this reward of up to £5,000 for information passed anonymously through the charity’s 0800 555 111 number which leads to the arrest and conviction of those responsible for the crime.
Senior regional manager for Crimestoppers, Sue Langley, said: “Mr Ross was a private individual who was well-known in Corby due to his business interests, so this murder has shocked a lot of people.
“The person or people responsible for this assault should not be allowed to get away with this crime and I am confident somebody knows who is responsible.
“I would urge anyone with information, no matter how small they think it might be, to contact Crimestoppers anonymously, safe in the knowledge that their identity will never be revealed.”
Mr Ross, who was originally from Kettering, was a partner in the new Rubix nightclub in Corporation Street, Corby, which opened just days before his death. He had also worked in the area as a taxi driver and a doorman.
Mr Ross’ mother Pauline Taylor and his brothers Niall and Glen have spoken of their heartbreak and urged the public to help police catch the killer.
A statement released by the family said: “All we ask is that we can lay him to rest knowing the people responsible for this are brought to justice.
“We need people to come forward with information regardless of how trivial they may think it is. That information could be vital to the investigation and help us get closure.”
Anyone with information is asked to contact Crimestoppers anonymously on 0800 555 111 or use the secure online form at www.crimestoppers-uk.org.
Police can be contacted by calling 101.
