The investigation into the death of Christchurch man David Bridgwater has taken a new turn with police searching the Avon River on Wednesday as items of interest including a gun remain missing.
The National Police Dive Squad will be carrying out a search of a segment of the Avon River, police confirmed.
Bridgwater, 38, was found dead on Carisbrooke St in the suburb of Aranui in the early hours of the morning on January 4. His car was found still running on a nearby street.
He died as a result of gunshot wounds, police said.
Exactly three weeks later, 51-year-old woman had been charged with accessory after the fact to murder. No one has yet been charged with his murder.
However, police are still looking for items of interest in the investigation dubbed Operation Walter, including a gun.
"Several people have been to be spoken to and as the investigation continues, we expect to speak with a number of others and carry out further searches in other areas of interest," Detective Senior Sergeant Colin Baillie said.
"We are committed to thoroughly investigating the death of Mr Bridgewater.
"Our thoughts are with the family of Mr Bridgwater, his mother, brother and children who are still seeking answers as to what happened."
A few days after his death, Detective Inspector Nicola Reeves told reporters Bridgwater's family was "really shocked" about what had happened.
"They're devastated about the news of their son, their brother... he's a father. They're coping very well under the circumstances, it's very early days. They've got a really long road ahead of them," she said.
Anyone with further information is urged to contact Police through 105 referencing Operation Walter. Alternatively, information can be given anonymously via Crimestoppers on 0800 555 111.
