The Indiana grandfather charged in the death of his toddler granddaughter after she fell from a cruise ship’s 11th floor window in July said Wednesday that his colorblindness may have been a contributing factor in the heartbreaking incident, a report said.

Asked if he knew windows on the Royal Caribbean’s Freedom of the Seas are tinted to distinguish whether they are opened or closed, 50-year-old grandfather Salvatore Anello revealed his medical condition to CBS News.

“I’m colorblind. I don’t know. I just never saw it. … I’ve been told that that’s a reason that it might have happened.”

“I thought there was glass. I still say it to myself, it’s just, I kind of relive it all the time, and I just thought there was glass there. I don’t know what else to tell you,” he continued.
