The identities of four people killed in the blast at a Chevron facility in Pembroke Dock have been released by police Police have named the four people killed in a blast that ripped through an oil refinery in Wales. Dennis Riley, 52, Robert Broome, 48, and Andrew Jenkins, 33, all from Milford Haven, and Julie Jones from Pembroke, were killed in the Chevron explosion on Thursday. Dyfed Powys police said a fifth person is in a critical but stable condition in hospital, but did not release their name. A joint police and Health and Safety Executive investigation is being carried out into the blast after it tore through the refinery in Pembroke Dock, south Wales. Maintenance work had been carried out on a storage tank which exploded at about 6.20pm on Thursday, damaging an adjacent vessel. Detective Chief Inspector Martin Davies, the senior investigating officer, said: “The bodies of the deceased were removed from the scene Friday evening. We are now working with forensic experts to formally identify the bodies.” The identification process was hampered by the nature of the incident and it is thought it could take several weeks. “Our specially trained officers have been supporting the families and next of kin of those who tragically lost their lives,” Ch Det Insp Davies said. “A fifth casualty remains in a critical but stable condition in hospital. The family have asked police not to release the name or any other details at this stage, and the media are kindly asked to respect the privacy of all the families affected by this incident at this difficult time.” Ch Det Insp Davies said family liaison officers made contact with each family’s next of kin as soon as the dead were identified. He added Chevron was urged not to directly contact the victims’ families in the immediate aftermath of the incident. “Due to the processes the police need to follow in the early stages of such an investigation we asked Chevron not to contact the families directly, but to liaise with ourselves and we would pass on any messages,” he said. “This is standard practice in such an incident.” He said the request was to be withdrawn Saturday afternoon, and the company will be able to get in touch with the families.
