A mystery blonde woman who may have been one of the last people to see murdered Les Ross alive is being sought by investigators.
The Corby nightclub boss was found murdered on Monday, December 17, 2012, at the Village Inn Express in The Jamb in Corby old village.
The previous evening - Sunday - he had been working at the Rubix Nightclub that he owned in George Street.
This morning, police officers revealed the new information on on the BBC Crimewatch Roadshow.
They said that after he left the club at about 2am on the Monday, he was seen talking to a blonde woman in a black dress.
Detective Chief Inspector Martin Kinchin said: “We believe that Mr Ross left Rubix in the early hours of the morning between 1am and 2am and he may have spoken to a blonde female in a black dress.
“We’d like to speak to that woman.
“She may have been one of the last people to see Mr Ross alive.”
Mr Ross, a popular cab driver, is believed to have gone back to the Village Inn Express hotel after his night in the club and communicated with friends normally early the next morning.
But he failed to turn up for a taxi run at about 7.40am and was discovered beaten to death at 2.40pm by hotel staff.
A 40-year-old Corby man was arrested on suspicion of the murder of Mr Ross and last July a further six men from the town were arrested in connection with the case.
They have all been released without charge and are no longer on police bail.
Despite a reward of £10,000, national coverage of the case on BBC’s Crimewatch programme and dozens of police appeals for information, no one has been charged with the murder.
Mr Ross’ brother, speaking for the family on the anniversary of his death in December, said: “This has been a terrible year for us. It has been frustrating that we have not been able to see justice done for David.
“There is someone out there who knows something.
“We are appealing for anyone with information, even if it is just a rumour, to come forward and speak openly and candidly to the police.
“It may be something they think is insignificant, but that could be the information needed to make a breakthrough.
“Coming up to the first anniversary of David’s death, it is difficult but we’ll be together on Tuesday to visit David at Kettering Crematorium.”
On December 14, just days before Mr Ross’ death, his Corby home was broken into.
Among the items stolen were an iPhone, a Blackberry Playbook and a laptop computer.
Police said it was not an opportunist crime but a planned break-in.
Mr Ross moved into the Village Express Hotel after the break-in but, despite trying to keep his whereabouts quiet, someone found out where he was staying.
Anyone who knows who the blonde woman may be can call police on 101 or Crimestopppers on 0800 555 111.
