A woman has been jailed for 10 years and six months over the deaths of four paddleboarders in Wales. Nerys Bethan Lloyd - a former police officer - pleaded guilty last month to four counts of gross negligence manslaughter and one offence under the Health and Safety at Work Act. Paul O'Dwyer, 42, Andrea Powell, 41, Morgan Rogers, 24, and Nicola Wheatley, 40, died after they got into difficulty in the River Cleddau, Pembrokeshire, on 30 October 2021. The four had been part of a stand-up paddleboarding tour when their paddleboards went over a weir in Haverfordwest, during "extremely hazardous conditions". The tour had been organised by Lloyd, owner and sole director of Salty Dog Co Ltd. The Crown Prosecution Service (CPS) said in a statement that an expert had concluded the tour "should not have taken place". Mr O'Dwyer initially exited the water but re-entered the river in an unsuccessful attempt to rescue the others. Ms Powell was taken to Withybush Hospital where she died of her injuries six days later. 'Extremely dangerous' Paddleboarding expert Andrew Gratwick said in his written evidence that he considered the weir to be "an extremely serious risk which should have been very obvious to any competent instructor". The court heard that neither the defendant nor Paul O'Dwyer had a "suitable qualification for this kind of activity" and that the "final decisions to take part" were hers. Prosecuting, Mark Watson KC, said he accepted Mr O'Dwyer "bears a share of the responsibility" but that the defendant was "primarily responsible for the needless loss of life". During periods of high water levels, Haverfordwest's weir "becomes extremely dangerous with high potential for loss of life", according to evidence submitted by the local kayak club's health and safety officer. One bystander, who had lived by the side of the River Cleddau for around 35 years said "he could not recall seeing the river ever flowing so strongly". "All seven participants had been completely taken by surprise by the presence of the weir and in a chaotic episode of some twenty seconds, they were all carried over the weir crest by the strong current," Mr Watson said.

Pic: PA A voice message service on the day of the incident recorded Lloyd as having said "It's my fault 100% I probably shouldn't have gone on the water." In the back of the ambulance, she was overheard telling friends that she was "going to jail for this". In mitigation, David Elias KC said Lloyd had "essentially dived back into life to try and block out what had happened". He said she had no previous convictions, was of good character, had attempted to assist the victims and had expressed remorse. 'Blatant disregard' Sentencing Lloyd at Swansea Crown Court on Wednesday, Mrs Justice Stacey told Lloyd that the weir presented an "obvious and extreme danger" and that she "showed a blatant disregard" for the risk of loss of life. "This was not a monetary lapse, your whole approach to health and safety was lax," she added. The judge said there were Met Office weather warnings at that time, as well as a flood alert in place through Natural Resources Wales. Mrs Justice Stacey said the footage of the incident was "too distressing to be shown in court". "Having studied it, I am sure that you made no attempt to investigate or paddle to the steps which were visible from the river." The judge said she was certain that neither Lloyd nor Mr O'Dwyer intended "any harm to any of the participants" but that her "whole approach to basic health and safety was abysmal".
