Detectives have released more details about those responsible for the execution-style killing of Upper Hutt woman Lois Tolley.
Four men walked into a Upper Hutt flat on December 9 where they stabbed Lois Tolley before shooting her at point blank range.
Locals Newshub spoke to in this normally quiet neighbourhood said they were concerned those responsible still hadn't been caught more than a month after the killing.
"Every time we walk past I would say 'well they haven't got them yet'. It's a horrible feeling knowing what happened in there and they haven't caught them yet," say local residents Rinay Bentley and Karen Reder.
Police are still trying to piece together the full story of what happened that night.
The reaction from one of those men as they left was overheard by neighbours.
"He's stopped outside calling out 'what have we done?' Swearing and saying 'what have we done?' so there's something playing on his mind," says Senior Sergeant Glenn Barnett.
Snr Sgt Barnett is hopeful this man's conscience will compel him to come forward.
Police have released descriptions of each suspect.
One was tall, skinny, and wearing baggy clothes. The second was shorter, and also wearing baggy clothes. The third was a tall man in dark clothing. And the fourth was believed to be a younger man.
Police have also said one or more women were involved and several they've spoken to have links to gangs, however a motive is still unknown.
Cars were also spotted near Ms Tolley's house and investigators want to hear from anyone who spotted them.
Detectives are continuing to trawl through CCTV footage taken from seven cameras in the area and say it's only a matter of time before they catch Ms Tolley's killers.
