Police scan dam floor as search continues for missing Brisbane judge
Police searching for a judge who disappeared in Brisbane have used sonar scanning equipment to map the floor of Enoggera Dam.
The search teams will resume the hunt on Friday, with plans to shift the main search area further west.
Superintendent Christopher Stream said during the five days of the operation, which began on Sunday, more than 100 people had scoured dense bushland for any sign of Guy Stephen Andrew.
The 55-year-old Federal Circuit Court judge was last seen at his home in north Brisbane early on Sunday and investigations suggested he drove towards Mount Coot-tha, where he regularly took morning walks.
The search has been hampered by "extremely heavy [and] difficult to traverse" terrain at times, with the police helicopter's infrared camera and water police's sonar scanner being used.

"The terrain has been extremely difficult, there have been a number of dams as well as the reservoir that have been searched using side scan sonar by the dive squad," Superintendent Stream said.
"That technology does give quite a detailed picture of underwater imagery ... and the dive squad officers report that those searches were quite extensive throughout the dam.
"We have used PolAir during the early part of the search, but due to the density of the foliage and animals and walkers in the area [giving off heat signatures], that has proved rather difficult.
"The medical advice is that if Mr Andrew has access to some form of water, then there is continuing survivability.

"However, if he were to be injured or in some form of distress, that is concerning, which is why we have committed the level of resources to this point."
Those involved in the search so far include police officers on foot, on motorbikes and all-terrain vehicles, police divers guided by sonar mapping, police drones, SES personnel on foot and on boats, community volunteers along with Mr Andrew's friends and family, Department of Environment and Science rangers, Brisbane City Council workers, Seqwater officers and 30 ADF personnel.
The Walkabout Creek Discovery Centre has provided rooms for authorities to set up their command post to co-ordinate the search effort.
On Thursday, Superintendent Stream appealed for dashcam footage taken between 3.30am and 6am on Sunday on Waterworks Road, Dillon Road and Payne Road that might show Judge Andrew or his white dual-cab Toyota Hilux.

"There have been a number of reported sightings ... [but] none of these inquires have led to the location of Mr Andrew," he said.
Anyone with further information or dashcam footage should contact Policelink on 13 11 44.
Superintendent Stream said Mr Andrew's family were "obviously very distressed" but they continued to "hold out hope that [he] will be located".
