On 23 March 2007, Pakistan players and officials were questioned by Jamaican police and submitted DNA samples along with fingerprints, as part of the routine enquiries in the investigation into Woolmer's murder. Three days after leaving the West Indies for Pakistan, via London, the Pakistan team were ruled out as suspects. The deputy commissioner of Jamaican police. Mark Shields, the detective in charge of the investigation, announced, "It's fair to say they are now being treated as witnesses." "I have got no evidence to suggest it was anybody in the squad." A memorial service was held in Sacred Heart Church, Lahore, for Bob Woolmer on 1 April 2007. Among the attendees were Pakistan players and dignitaries, including Inzamam-ul-Haq, who was quoted as saying, "After Woolmer's family, the Pakistan team was the most aggrieved by his death." After the World Cup ended, serious doubts were raised about the investigation, with increasing speculation that Woolmer died of natural causes. This has now been accepted as fact, and the case has been closed.
