A friend of Levi Bellfield said today that he helped clear out bags of clothes and a mattress the day after Milly Dowler was killed.
The 13-year-old is alleged to have been snatched off the street and murdered by Bellfield the day before in a flat in Walton-on-Thames, Surrey, in 2002.
Malcolm Ward, who was 20 at the time, said he helped him load the items into a van which was driven to Bellfield's new address.
Mr Ward said he had been working with Bellfield at a club in Uxbridge and was asked to help decorate the kitchen of Little Benty, West Drayton, because he was moving.
But after three hours, Bellfield drove him to Walton to move items, he told the Old Bailey.
When they got to Collingwood Place, Mr Ward said: "He was grabbing stuff, clothes, tracksuit bottoms and hoodies, and putting them in two black bags in the bedroom."
They were put into the van along with a mattress from the same room, he said.
"When I left, the mattress was still in the van."
Bellfield was not his "usual jolly self" but had been "quieter than normal".
Mr Ward added: "He was sad, not happy. He may have had something on his mind."
Bellfield, 43, denies abducting and murdering Milly, 13, and attempting to kidnap 11-year-old Rachel Cowles in March 2002.
Milly's remains were found in woods 25 miles away after six months.
Bellfield, a former wheelclamper and bouncer, was convicted in 2008 of the murders of Marsha McDonnell, 19, and Amelie Delagrange, 22, and the attempted murder of Kate Sheedy, 18.
