The detective leading the investigation into David Brickwood’s death has appealed to people who know the identity of his killer to “search their conscience” and contact police.
Mr Brickwood, aged 74, suffered fatal stab wounds after he was violently attacked at his home in Lindsay Avenue, Abington, in the early hours of Saturday, September 26.
A major investigation team which was set up following the murder and they are following a number of leads.
Detective Chief Inspector Mick Graham today said today that five people have been arrested as part of the murder inquiry but nobody has been charged.
He said: “Mr Brickwood’s family are clearly still devastated by the way he died and I would appeal for people who have information about who may be involved to look to their conscience and come forward to the police.
“I would particularly ask family members who may have seen relatives acting oddly the day after the murder, or who came home with blood on their clothing, to consider, if this was your father or grandfather who had died, how you would feel and I would appeal for them to come forward.”
Discussing the motive for the murder, DCI Graham said he did not believe the people who went into Mr Brickwood’s home went in there with the sole intention of causing his death.
One of the key lines of investigation is two Ford Focus cars which were seen being driven closely together in the Abington area at the time Mr Brickwood died.
It is hoped the people who were driving these vehicles, or the passengers in them, will come forward to help with the investigation.
In a bid to encourage people to come forward, the independent charity, Crimestoppers, has offered a reward of up to £10,000 to people who provide information which leads to the arrest and conviction of Mr Brickwood’s killers.
DCI Graham said: “I hope the reward will provoke a response from people who may have information.
“It gives people an opportunity to tell Crimestoppers something they may not want to tell the police and hopefully it will help the family get some closure.”
Over the coming days, officers will also deliver hundreds of leaflets to homes in the Abington area appealing for anyone who knows anything about Mr Brickwood’s death to come forward.
Witnesses, or anyone who knows anything about Mr Brickwood’s death, can call Northamptonshire Police on 101.
