IPSWICH, England Dec 12, 2006 (AP)— British detectives hunting a serial killer who preys on prostitutes discovered two more bodies Tuesday, police said, bringing the total number of victims to five.

"We can only fear the worst," Detective Chief Superintendent Stewart Gull of Suffolk police said. "The natural assumption is that these are the two missing women."

As part of the investigation into the deaths of Gemma Adams, 25; Tania Nicol, 19; and 24-year-old Anneli Alderton, detectives were also searching for Annette Nicholls, 29, and Paula Clennell, 24. Both had also worked as prostitutes in Ipswich.
