Newborn girl plunges from window of NYC apartment building

A newborn girl with her umbilical cord still attached has plunged from the window of a New York City apartment building, and police are questioning her mother.

Officers responded to the seven-floor building in the Bronx yesterday after an emergency services caller reported that an infant had fallen out of a window.

The baby was pronounced dead by first responders in the building's rear concrete courtyard.

Police say the baby showed signs of trauma.

No arrests have been made.

A secretary for the building's landlord says police are investigating and declined to comment further. She said 50 people live in the building.
