A man whose body was found among rubbish at a waste transfer site was named by police.
A post-mortem examination revealed that Scott Williams, 35, died of crush injuries before being discovered at the Sussex Waste Recycling Ltd site in North Quay Road, Newhaven, East Sussex.
The 35-year-old, from Wembley, north west London, was reported missing an hour after his body was found by a member of staff.
A spokeswoman for Sussex Police said detectives were still investigating how Mr Williams came to be in the dustcart, which contained rubbish collected from wheelie bins around Brighton.
He had been out with a friend in the city on Saturday night and was seen in various pubs until the early hours.
The spokeswoman said: "It is assumed that Scott, who had been out with a friend and was seen in public houses in the city until 1am on Sunday, had been in one of the wheelie bins.
"Police are investigating how he came to be there and are treating his death as unexplained rather than suspicious."
Staff at Sussex Waste Recycling Ltd were sent home for the day following the grisly discovery just after 7am.
Dave Ely, a director at the company, which trades as Rabbit on an industrial estate in the port town, said rubbish is taken on to the site by its own vehicles on behalf of local councils and also by third party firms.
He said: "This particular dustcart was owned by a third party company which had tipped a load of black bin waste from the Brighton area.
"After it left, staff started looking through the waste and one of them saw what he thought was a body.
"At that point the police were alerted and that is as much as we know."
He added: "We have no idea when the vehicle collected the waste, whether it was over the weekend or some time last week."
