Earlier, The Sunday-Mail reported that police had conducted tests at the western suburbs roundabout central to the investigation into the murder.
Traffic was stopped for about 20 minutes on Friday night so police could time a white vehicle going around the Kenmore roundabout, and driving up Brookfield Rd, where the victim lived.
The roundabout, which is monitored by a CCTV traffic camera, is on the main route between Mrs Baden-Clay's home and the Kholo Creek Bridge on Mt Crosby Rd at Anstead, where her body was found last Monday.
Police have continued to renew calls for anyone who drove in the vicinity of the Brookfield and Moggill roads roundabout, between 11.30pm on April 19, the night Mrs Baden-Clay went missing, and 4am the next morning, to come forward.
