A significant theory has emerged after police identified the three sisters who lost their lives in the Brighton beach tragedy.

Jane Adetoro, 36, Christina Walter, 32 and Rebecca Walters, 31, from Uxbridge, London, were pulled from the English Channel at around 5.45am on May 13 after emergency services received reports of people struggling in the water. All three were pronounced dead at the scene.

Investigators are now thought to be exploring the possibility that at least one of the sisters waded in too deep and lost her footing when the shingle dropped away beneath her. Coastguards believe the women may have been swept away from the shoreline after tumbling off the coastal shelf.

Brighton locals say the seabed plunges sharply just a short distance from the beach, making it perilous to wade out too far. Regular warnings are issued to visitors urging extra caution, particularly around the Palace Pier area where the shingle is at its steepest.

In a heartfelt tribute, father Joseph said the girls' lives "ended so tragically far too soon" - and said "no words can truly describe the pain" of "losing three daughters in the prime of their lives".

He said there are days when the grief feels "unbearable" but he holds onto the memories they shared and "the bond that death can never take away".

A statement released through police said: "Jane, Christina, and Becky were more than daughters to me; they were my joy, my strength, and the beautiful light that filled our family with happiness and love.

"Each of you was unique and precious in your own special way. Your smiles brightened dark days, your laughter brought comfort, and your presence made life more meaningful.

"Though your time on earth was short, the impact you made will remain in our hearts forever."

Chief Superintendent Adam Hays, Divisional Commander for Brighton and Hove, said: "The thoughts of everyone at Sussex Police are with the family of Jane, Christina and Rebecca following this devastating loss.

"I know this incident has had a profound impact on the local community in Brighton, and across the country and I'd like to reassure the public we will leave no stone unturned in our investigation to understand exactly what led to the tragic events of that Wednesday morning.

"This investigation will continue in earnest, with Jane, Christina and Rebecca's family at its centre. I would ask that they are given the privacy to come to terms with this terrible tragedy."
