PHUKET: A British traveller named as Christopher Alan Ware is being questioned again by police investigating the savage murder of two British tourists, Phuketwan learned today from police sources.

DNA samples are expected to reveal today whether Ware is a prime suspect or whether several Burmese remain under suspicion for the slayings of Hannah Witheridge, 23, and David Miller, 24.

Ware left the holiday island of Koh Tao yesterday but returned this morning in response to a request from police. Later, he was taken to the beach where the murder took place.

Today brought more unusual twists in the pursuit of the killer or killers.

Region 8 Police Commander Panya Mamen told Phuketwan: ''David Miller's luggage contains a pair of bloodstained pants, which adds to the mystery.

''There was also blonde hair on a mobile telephone police have now located.''

It's understood that Miller and Ware shared a room at the Ocean View Bungalows, where Hannah Witheridge was also staying.

Doctors have been asked to determine whether cuts on Ware's hands are old wounds or fresh cuts. A hoe was used to kill the British travellers.

Another report today, so far unconfirmed, says that blonde hair has been found in one of Hannah Witheridge's hands.

Both bodies are expected to be autopsied in Bangkok today as more than 300 police conduct further inquiries on the Thai holiday island where the two bodies were found on a beach early on Monday.

Police conducted tests and found that sound does not travel far from the cove where the bodies were found because of rocks that surround the small sandy beach.

Phuket detective and forensics specialist Colonel Santi Chainiramai is among a number of police called in from surrounding jurisdictions to solve the murders as fast as possible.
