59-year-old Anthony Richardson is charged with acting in a manner injurious to a child under 17.
Police said officers responded to Cohen Children's Medical Center on 76 Avenue around 7:15 p.m. and hospital officials informed them that Richardson drove 3-year-old Jaylynn Evans to the hospital himself.

She arrived unconscious and unresponsive with no obvious signs of trauma and was pronounced dead.
Richardson is the grandfather of the girl's best friend, police said.
He was apparently watching over the girls in his apartment on East 138th Street in the Bronx when he found the 3-year-old unconscious.
He bypassed nearby hospitals and did not call 911 on his way to Queens.
Richardson told detectives he frequently takes his own relatives to the hospital in Queens and rushed the girl there because he knew it was home to a leading children's hospital.

The Medical Examiner will determine her cause of death and if the delay to get her help played a role.
