Deputy &13;Commissioner of Police Mark Shields said his team were considering getting DNA &13;samples from all persons who were in the hotel at the time of murder, including &13;the West Indian and Ireland players.
For that investigators will have to &13;travel abroad, including to other Caribbean islands and try to get useful bits &13;of information by interviewing the players and officials.
It was not &13;clear how many people were staying in thehotel when Woolmer was killed. Besides &13;Pakistan team, players from the West Indies and Ireland squads were also staying &13;there, as well as dozens of fans and international journalists.
Jamaica &13;police have also analysed Woolmer's laptop and have found no evidence of &13;match-fixing and betting.
Shields told a news conference at Pegasus &13;Hotel here that all possible motives were being considered, including &13;match-fixing.
''We have Bob Woolmer's computer. We are looking at what &13;is on the hard drive. We're exploring the possibility of match-fixing, but &13;that's only one line of inquiry,'' Shields said.
Woolmer was found &13;unconscious in his hotel room a day after Pakistan's shock defeat to Ireland and &13;Shields said the police will look into the betting odds for the match. &13;
Investigators are also relying on the footage from the hotel &13;surveillance camera, for which Shields pointed that it would be a very time &13;consuming process, having to study the footage frame-by-frame.
''At the &13;end of it, it might be that we might identify a suspect or suspects,'' Shields &13;said.
Meanwhile, after eight days of speculations, Jamaican Police have &13;finally excluded Pakistani players from their list of suspects in the &13;high-profile murder case.
Shields, a former Scotland Yard detective, said &13;that his department has collected enough evidence to rule out the Pakistani &13;players as suspects in the murder of their coach.
''It's fair to say they &13;(Pakistani players) are now being treated as witnesses,'' Shields &13;said.
''We have got no evidence to suggest it was anybody in the squad,'' &13;he added.
Pakistani players who were questioned, finger-printed and &13;swabbed for DNA before being allowed to leave Jamaica on Saturday. The way &13;Pakistani players were interrogated led to widespread rumours that the Police &13;have placed some of them among the list of prime suspects.
The police's &13;belief that Woolmer was killed by somebody he knew only added fuel to &13;fire.
Shields said the authorities have the option of ordering back any &13;Pakistani player or official during any stage of the investigations. &13;
''The reality, as I've said before, is that there are many potential &13;suspects in this investigation and even more potential witnesses, and we are &13;nowhere near the stage of being able to start naming names in terms of &13;suspects,''he added.
Shields also rejected a British newspaper report &13;that Police were now looking for three Pakistani fans -- Hamid Malik, Jundie &13;Khan and Efran Chaudhray -- who reportedly left Jamaica immediately after the &13;murder.
The three were described as gofers who brought players halal food &13;and drove them around Jamaica and believed to have had access to the 12th floor &13;of Pegasus Hotel, where Woolmer's room was.
