Sexton was out with friends in Brighton, England, on the night when he fell and hit his head.

Newspapers reported that he had climbed on top of a telephone booth and fell to the ground. Sexton was rushed to the hospital that night in critical condition and was later transferred to a neurological facility in Haywards Heath, England. Few details have emerged, but he reportedly never fully recovered following the accident.

Sexton was the youngest son of Neeson’s sister Bernadette.

His death comes nearly 10 years after Neeson lost his wife, Natasha Richardson, who suffered a fatal head injury while skiing in Canada in March 2009. She was 45.

Speaking to Irish TV station RTE in 2017 about the death of his wife, to whom he had been married for 15 years, Neeson said: “There are periods now in our New York residence when I hear the door opening, especially the first couple of years … anytime I hear that door opening, I still think I’m going to hear her.”
