Rafael Sanz lost his wife last week, and yesterday, he lost his newborn son: Baby Sean Michael Justin Sanz, born two months premature after his mother was hit by an out-of-control van on August 14, died around 1 p.m. Mayor Bloomberg said, "Our hearts and prayers go out to the child's father, Rafael Sanz, and to all those who loved Donnette and her son. Their already heavy burden of grief has been terribly compounded." Rafael Sanz, who had been hopeful of his son's survival, told the Daily News, "My baby meant everything to me," and raged about the unlicensed, ex-con driver who hit his traffic agent wife, "I hope the driver dies a horrible death."
