The family of David Currier have made a fresh plea for information after detectives announced that they had relaunched the murder inquiry into his death at Bromsgrove in 2009.

The decision to reopen the investigation follows a periodic ‘cold case’ review by West Mercia Police’s Major Crime Review Team.

New information has been released about the circumstances surrounding his death and a £10,000 reward is still on offer for information leading to arrest and conviction of those responsible.

Mr Currier died after receiving a stab wound in the leg at 285a Birmingham Road, Lickey End, Bromsgrove, in the early hours of Saturday, 7 February, 2009, while his six-year-old son slept upstairs.

Making a fresh plea for information Mr Currier’s sister Lorraine Nicholls, a 41-year-old sales manager, said that his death had had a shattering impact on the family.

She said that his son, who is now eight and living in the West Midlands with his mother, constantly spoke about his father.

She said: “He talks about his dad all the time although he never speaks about that night. He’s happy-go-lucky and gets on with things but often wonders if he looks like his dad, who he’s the spitting image of.

“He says he wishes he could go up into the sky and bring his daddy back alive and often blows kisses up into the air for him.

“When he gets pick and mix sweets he saves the Cola Bottles and puts them on his dad’s grave because he knows they were his favourites.

“And orange is his favourite colour because his dad had a Ford Focus which was that colour.”

“We still don’t know the reason why they did it (killed him) – it’s hard not knowing. Did he say something to them, was he scared, was he trying to look out for his son?

Mr Currier’s mother, Karen Barry, who lives in Birmingham, said: “I think that if he was on his own when they broke in he would have escaped out the back rather than confronted them but knowing his son was there he wouldn’t have moved an inch.

“If we had lost him through an accident, there’s a reason. If it was a terminal illness, there’s a reason. It’s the senseless taking of a life that you can’t come to terms with.

"It won’t make me feel better if someone is arrested for his murder but it will bring closure. We are appealing for anyone who knows anything at all about my son’s death to contact the police.”

Karen Nicholls added: “It’s the hardest thing a family could ever go through, losing a brother, son, uncle.

"He’s there one day, gone the next without you being able to say ‘I love you’ or ‘sorry’ or anything that needed to be said. We have lost every chance of that but we think about him every single day.

“Someone out there knows something about the events that night and who the people were who were seen on his drive and I would plead with them to tell the police now.”

Mr Currier’s body was found in his kitchen the following day. Evidence in the kitchen indicated someone else had been there.

There were signs of a forced entry at the front door and a witness told of hearing the sound of breaking glass coming from the direction of the property that morning.

Police were also told that four men had been seen standing beside a white transit van on the snow-covered driveway of the home at about 12.45am on the morning Mr Currier was found dead.

Detective Chief Inspector Graham Smith, from the West Mercia Police Major Crime Review Team, said: “After a careful study of all the evidence, including forensic samples, and fresh interviews with witnesses, we took the decision to formally re-open this investigation which as far as West Mercia is concerned is a rare unsolved murder case. "

He revealed that officers had discovered cannabis plants and cultivation equipment at the property and this was one of a number of lines of inquiry detectives were focusing on.

“The full circumstances surrounding Mr Currier’s death are still not known but we are of the firm opinion that other people were present in the house at or around the time of his death.

"Clearly someone out there knows what happened and the passage of time and changing circumstances may make it easier for them to come forward now and tell us.

“A £10,000 reward is still being offered by us for information leading to an arrest and conviction in connection with this inquiry.

“It has been very difficult for his family to cope with his loss and not knowing exactly how or why it happened. We are determined to trace the killer and bring some closure for them.

“The smallest of details could yet hold the key to this investigation so if you know anything that you have not yet passed on to the police then please get in touch.”
