A 26-year-old woman who claims to have murdered her Sussex pensioner husband in Gambia appears to be "depressed and remorseful", African police have said.

Kate West first said five Nigerian men killed William West, 76, at their Sanyang home. Then she claimed she knocked him out and set him alight.
Gambia Police spokesman Aziz Bojang said the possibility of accomplices being involved had not been ruled out.
Mrs West who is in custody charged with murder may appear in court next week.
She had taken part in a reconstruction of the crime in which she showed police how she killed her husband, Mr Bojang said.
He said: "When I spoke to her she appeared very depressed and remorseful, not at the condition she now finds herself in but because of what she has done.

"I think she is now realising the consequences of what has happened and how it will affect her life."
He added: "Her claim that she acted solely on her own seems to collaborate with evidence we have found on the ground.
"But whether that story is true is still to be fully determined.
"We are not ruling out other possibilities even though she has told us she was responsible for the murder. She is still helping us with our inquiries."
British forensic experts will fly to Gambia next week with samples of Mr West's DNA.

The Dublin-born businessman, from Hastings, East Sussex, had lived with his wife in a luxury four-bedroom, beach-side home in the fishing village of Sanyang.
Mr West's will showed that Mrs West, his second wife, was in line to inherit the Gambian property they shared. His first wife, Doris, died in 1994.
