BRADFORD, England, June 1 (UPI) -- British police have questioned suspected serial killer Stephen Griffiths about a fourth dead prostitute, the woman's mother said.
The victim was Rebecca Hall, whose battered body was found in an alley in Bradford in 2001. She was 19.
"I have spoken to the police and they have been asking him about Becky but he wouldn't say anything. He didn't answer them," Hall's mother, Angela Hall, 56, told the Telegraph.
Griffiths, 40, of Bradford, has been charged with murder in the deaths of Shelley Armitage, Susan Rushworth and Suzanne Blamires.
All of the women had been prostitutes, investigators said.
Griffiths, who in court called himself the "Crossbow Cannibal," was arrested last week after surveillance footage from a building showed Blamires being killed with a crossbow.
On Monday, police recovered nearly all of Blamires' severed remains from the River Aire in Shipley along with a bag of hacksaws and knives, The Daily Telegraph reported. The remains of Armitage and Rushworth were not found.
