UPDATE 2pm: Missing Boulder bookkeeper Veronica "Ronnie" Messina's beloved shitzu dogs may be the key for detectives trying to find the 62-year-old mother who was last seen almost a fortnight ago.
Ms Messina was reported missing on June 28, and friends initially said they had not seen her since she left an Oroya Street business on June 23.
Detectives have since found security camera footage of Ms Messina in the Boulder Bunnings store about 1.30pm on June 25.
On Wednesday, a witness reported finding Ms Messina's dogs walking next to the Goldfields Highway between 5pm and 5.30pm on June 25. The witness returned the dogs to the address engraved on their collars, 62 Federal Road, Boulder, Ms Messina's home address.
"The person was travelling on the Goldfields Highway, heading north to Boulder, when they spotted two dogs running along the road verge towards Kalgoorlie," acting Det-Insp. John Hindriksen said. "Both were wearing collars, they were well cared for, both were clean and it would not appear they had been out there that long."
Acting Det-Insp. Hindriksen said the dogs were handed to Ms Messina's housemate, who left Kalgoorlie-Boulder on a train for a pre-arranged trip to Perth on June 26. Ms Messina's home was found unlocked and her dogs unattended on June 28.
"The location where the dogs were located is significant, and as such we also believe the Holden Commodore owned by Ms Messina may have been in that area at the same time," he said. "She was very close to her dogs . . and the fact they were out there and left out there is quite significant."
Ms Messina's car, with a distinct dent on the right front panel, was found abandoned and unlocked in a car park at Kalgoorlie airport on June 28.
This morning police searched bushland near Kalgoorlie-Boulder.
Mounted Police, SES volunteers and detectives from Kalgoorlie and Perth scoured a 4sq km area, about 10km south of Boulder on the Goldfields Highway.
The search centred on a truck bay near where Mrs Messina's dogs were found.
A number of abandoned mine shafts are also understood to be located in the area, which was searched from the air by police with a thermal imaging camera on Thursday night.
Two of her brothers pleaded for information yesterday. Her youngest brother Stan Traeger said the disappearance was causing considerable distress.
