The horrifying news came in just as New York City was waking up on a routine Tuesday morning: A jogger in a Queens park had spotted a lifeless baby in the grass and called the police.

Dozens of police officers quickly arrived to find a discolored infant on its stomach in Crocheron Park in Bayside.

It was lying next to a wall, raising the prospect that perhaps someone had thrown the infant over the wall and fled.

The authorities began releasing details — 3-month-old baby found, no heartbeat — and set up a crime scene as news crews arrived.
