Two sisters of the man charged in the 1979 disappearance of Etan Patz say their brother had said things years ago about hurting a child in New York.
Pedro Hernandez was charged Friday with murdering the 6-year-old.
Hernandez was 18 when Etan vanished. Police say he confessed this week to luring the child into the basement of a convenience store and strangling him.
His sister Lucy Suarez says that her brother long ago had told relatives that he had hurt a child. But she says he was never specific about what happened.
Another sister, Norma Hernandez, says she learned at some point that her brother had confessed to a church prayer group in the 1980s that he had killed a boy.
