Police investigating the disappearance of Sussex man Gary Hampson have completed a search of land in Surrey without any "significant find".
Mr Hampson, 42, from Portslade, was last seen dropping his daughter off at her mother's house on 6 January.
Specialist officers finished their search for "signs of disturbance to the land" in Dunsfold on Wednesday.
Sussex Police Det Insp Phil Mays said they would continue to review potential sites as part of their investigation.
He added: "I would like to thank members of the public both in Sussex and Surrey for their understanding and support while specialist search officers undertake a scoping exercise as part of the Gary Hampson murder investigation, including accessing private land.
"The scoping exercise around the area of Dunsfold was completed this morning and we are continuing to review further potential sites as part of this ongoing investigation.
"We are extremely grateful to the local community for their help."
Mr Mays also renewed the force's appeal for the owner of a red Ford Mondeo, that was seen at the garage in Little Western Street in January, to come forward.
Officers have already searched 16 locations near the A281 north of Cowfold near Horsham in West Sussex.
They have also searched a stretch of the River Adur between Henfield and Cowfold and a number of ponds.
