A 5-month-old boy in the Bronx was found dead in his crib, hours after his mother said he came down with a fever, according to police.

The mother told authorities she gave the baby Tylenol earlier in the evening to reduce the fever; when she checked on him around midnight, he wasn’t moving, and she called 911, police said. The home is in NYCHA’s Castle Hill Houses.

Paramedics found the boy unresponsive in bed and took him to Jacobi Medical Center, where he was pronounced dead, police said.

The baby did not have any immediate signs of trauma, and no foul play is suspected, police said.
