Luis Ortiz told the New York Post that he was at the hospital when paramedics rushed the boy there and that they were pumping his chest and working on him.

You could tell he was slipping away. They said the father was up there,but they didnt bring anyone else in. It was just heartbreaking. I have two kids of my own. They tried to do the best they could, Ortiz told the newspaper.

Authorities said the father did not live in the building.

Police investigating the deaths left the building in the mid-afternoon to photograph a gray Lexus RX350 parked nearby.
