A GRUESOME search is being carried out in Huddersfield for human remains.
Police divers and forensic experts are searching the River Calder and the Calder and Hebble Canal at Colnebridge for body parts belonging to a murder victim.
Adam Vincent, 33, is thought to have been killed and dismembered.
Parts of his body have already been found in Lincolnshire.
Mr Vincent’s leg was discovered on March 3, followed by a torso and an arm. His other limbs and head remain missing and searches are also continuing in Lincolnshire.
But now the search has switched to West Yorkshire and to the two waterways at Colnebridge.
It is believed police have been given detailed information about where some of the remains may have been dumped.
Detectives from the Humberside Police Major Incident Team are working with officers from West Yorkshire Police in order to carry out searches in the Colnebridge area.
It follows a possible sighting of a white-coloured Ready Rent a Van Ford Transit van at the scene.
Police believe it may have been used to dispose of Mr Vincent’s body.
The vehicle was seen in Colnebridge between March 1 and 7.
The searches include West Yorkshire Police underwater search officers and are expected to be taking place for the next couple of weeks.
The searches form part of the ongoing investigation into the suspicious death of the Grimsby man.
Det Chief Insp Mark Oliver said: “West Yorkshire Police are searching the River Calder and the Calder and Hebble Navigation in response to a sighting of the van.
“It is important for the family of Adam Vincent as well as to progress the investigation that we recover the remains and will do all we can to make this happen.”
Mr Vincent’s father Keith has said his son’s murderers have destroyed his and his family’s lives.
A human leg was discovered by a passer-by at Tetney Lock in Lincolnshire last Thursday and further remains were found by police on Friday and Sunday.
After post-mortem tests, police named the victim as Mr Vincent, formerly of Alexandra Road, Grimsby. Father Keith Vincent said: “Somebody out there must have a conscience.”
