Police have used CCTV footage to identify two vehicles of interest in the case of murdered Upper Hutt woman Lois Tolley.
The vehicles, a blue Subaru and a silver, lowered, sedan-type car with black wheels, were both seen in the area around Tolley's flat at the time of her death, Detective Senior Sergeant Glenn Barnett said.
Police want to hear from anyone who recognises the vehicles, or anyone who has information which might help to identify the vehicles' owners.
"The investigation team continues to review CCTV footage from the night that Lois was killed and we're confident that we will find more footage that captures the offenders and the vehicles used," Barnett said.
Police have also released descriptions of four suspects.
Suspect one is a tall male, around 1.88m with a skinny build, aged 20s to 30s. He was wearing dark, baggy clothing, a hoody with the hood up, dark, low-slung pants, and possibly white underwear. Police also say he was carrying a large, rectangular object.
Suspect two is a male, shorter than the first suspect, with a skinny build, who was wearing dark, baggy clothing.
Suspect three is a tall male with a lean build, wearing dark clothing, long dark pants, and a hoody with the hood up.
Suspect four is a male that "sounded younger than the other suspects" and is believed to be the man who was seen upset outside Tolley's flat, Barnett said.
"Police acknowledge that these descriptions are not very detailed, but we reiterate what we've said before - somebody knows who these people are, and they need to come forward and share what they know with police," Barnett said.
"As advised last week, police now believe it is also possible that one or more females may be involved, and that more than the four people sighted outside Lois' flat that night know what has happened and who is responsible for her death."
Anyone who has not yet spoken to police but who may have information that can help should contact the Operation Archer team based at Upper Hutt Police Station.
