Missing 11-Year-Old Mackenzie Swift Feared Dead After River Don Incident
Missing Boy Mackenzie Swift Feared Dead in River Don

An 11-year-old boy who has been missing and is feared dead after entering a South Yorkshire river has been identified as Mackenzie Swift. The youngster has not been seen since Saturday, May 30, when it is believed he entered the River Don in Mexborough.

A major search operation was launched to locate him, involving firefighters, mountain rescue teams, and an underwater search unit. Police have now had what they describe as a 'heartbreaking conversation' with his family, conveying that it is unlikely Mackenzie could have survived in the water for such an extended period. Authorities have no indication that he managed to get out of the water on Saturday.

South Yorkshire Police have stated they will continue searching for Mackenzie. The tragedy comes amid a spate of open-water fatalities during the UK heatwave, with at least 17 people, predominantly children and teenagers, losing their lives in the last ten days.

Police and Community Response

Doncaster District Commander, Chief Superintendent Pete Thorp, expressed the force's commitment: 'We will continue to do everything in our power to find Mackenzie and to support his family through this incredibly difficult time. They truly are living every parent's worst nightmare.' He added that specialist resources and organisations from across the region are being utilised, with officers remaining at the search site overnight and further operational activity resuming at first light on Tuesday morning.

Thorp appealed to the public: 'I understand members of the public are desperate to help, but I must ask that you leave this work to the professional search teams. Please do not put yourselves or others in danger by searching in and around water, and if asked to leave by officers, please understand this is for your own safety and to ensure our efforts focus solely on finding Mackenzie.'

Other Fatalities During the Heatwave

Earlier, the first image of 16-year-old Lillianna Tomlinson, who died after getting into difficulty in open water, was released. She lost her life after entering the River Tame near Kingsbury Water Park in north Warwickshire last Monday. Her devastated family paid tribute, stating: 'We're deeply saddened to be writing that Lillianna's life has been taken in the most tragic way. Our family is completely devastated and will be forever heartbroken.'

An online fundraiser set up by the mother of Lillianna's best friend describes the teenager as 'a bright, kind, and caring young girl who touched the lives of everyone who knew her.'

There were four more deaths on Monday as temperatures reached 34.8C at Kew Gardens, breaking the record for the hottest-ever May day. Among them were 13-year-old Reco Puttock, pronounced dead after being found in Leadbeater Dam in Halifax, West Yorkshire; 16-year-old Lillianna Tomlinson at Kingsbury Water Park; and heroic grandfather Phil Crow, 68, who died of a cardiac arrest while trying to rescue his wife and granddaughter at Tregirls Beach in Padstow, Cornwall.

Weather Shift

Temperatures have since dropped towards the average for the time of year following the heatwave. Forecasters said the first day of June would feel 'more like spring or autumn', with thunderstorms and cooler temperatures expected. Tuesday was the hottest May day on record for England and Wales, with 35.1C at Kew Gardens and 32.9C at Cardiff Bute Park. Met Office meteorologist Rebecca Mitchell confirmed the heatwave was 'over', adding: 'Ironically, it's the first week of meteorological summer starting, but it will be feeling much more like spring or autumn.' She noted a 'big change on the way', including rain, possible thunderstorms, and strengthening winds, with temperatures around 17-21 degrees Celsius, about 14 degrees lower than the previous week.

The Royal Life Saving Society has issued a plea for everyone to 'stop and think' before entering open water, in response to the tragic deaths.
