The search at a detached, whitewashed bungalow in Boothferry Road, Hull, came as detectives were given more time to question a man in connection with the disappearance of Miss Carver, 22, a computer operator.
Officers arrested the 23-year-old man, who works at a petrol station in Willerby, Hull, on Tuesday. The petrol station was sealed off and tests were being carried out by forensic experts.
The station is half-a-mile from the lane where Miss Carver's car was found with the keys in the ignition early on 5 March.
Officers in boiler suits carried spades into the back garden of the bungalow, which is the home of Maureen and Clifford Belcher and their son Craig, 23.Reuse content
