Police investigating the disappearance of a man in March 2010 have been searching a stretch of ground near the M4 again.
A man has been charged with the murder of Donavan Van Lill, a 29-year-old South African, but no body has been found.
Mr Van Lill, a personal trainer, had been living in Chippenham.
Officers were examining land close to junction 15 of the motorway, near Swindon, on Wednesday.
Martin David Sugden, 42, of Clanville Bar, Stanton St Quinton, pleaded not guilty to murdering Mr Van Lill at Bristol Crown Court in July.
His trial is due to start in Bristol on 14 March.
