“Daniel was one of the happiest kids you would ever meet,” his obituary says. “He enjoyed watching cartoons, especially Dinosaur King and Octonauts. He adored his baby brother, Ivan, and would never let him out of his sight.”

Ivan’s obituary says he was a happy child who was full of laughter.

“He always wanted to be held,” it says. “He was a momma’s boy during the day but wanted his daddy as soon as he arrived home.”
