Gambian police investigating the murder of an elderly man have met officers in Sussex to share facts in the case.
Police from the Gambia and Sussex visited William West's house
The body of William West, 76, of Hastings, East Sussex, was found near his holiday home in the village of Sanyang in the Gambia in July.
His wife, Kate, 26, has admitted his murder but could still change her plea, in which case a trial would go ahead. Three other men have denied the murder.
Sussex Police are liaising with Gambia officers who are running the inquiry.
Mr West's burnt body was found in a bag. His wife has previously told police that she knocked him unconscious and set fire to his body.
Officers visiting from Africa were trying to build up a picture of Mr and Mrs West's life together, and went to the couple's house in Hastings.
They also collected the results of forensic tests carried out by Sussex Police on soil samples taken from where Mr West's body was found.
Kate West said she knocked her husband out and burnt his body
Supt Demba Sowe, of the Gambian Police, said: "We don't have a lab to do DNA tests.
"Other examinations can be conducted there, but when it comes to DNA, that's a bit of an advanced technology which we don't have at home."
Det Insp Paul Phelps, of Sussex Police, said: "Mr West is a British subject and a resident of Sussex.
"It's important to Sussex Police that we bring justice to Mr West and also assist colleagues in the Gambia with the technology that we have here in the UK to strengthen their case."
Mrs West's next court appearance is due to take place before the end of October.
