The newborn baby girl found dead in a Bronx courtyard was still alive when her mom tossed her out of a seventh-floor window, law enforcement sources said Tuesday.

Charges were pending against Jennifer Berry, 33, of Yonkers, who had claimed to cops that she gave birth to a stillborn baby in the shower — then threw the child out of her boyfriend’s bathroom window on Monday afternoon.

But the city’s Medical Examiner concluded that the infant was still breathing in the University Heights apartment — and ruled the death a homicide.

“The cause of death is multiple blunt force injuries,” said New York City Chief Medical Examiner Dr. Barbara Sampson.

The wife of the building’s superintendent stumbled upon the baby when she was taking out the trash, and cops were called to the scene around 2:45 p.m.

Soon after Berry tossed the child, her boyfriend, 28-year-old Giovanni Johnson, discovered her sitting in the shower next to a pool of blood, which she insisted was just from her menstrual cycle, sources said.

Johnson told cops he asked if she was pregnant, and she told him she’d had an abortion about four months ago.

“I suspected she was pregnant, but I didn’t know for sure,” Berry’s stunned mother told The Post. “I’ve been waiting for her to say something to me.”

Berry, who was held without bail at her arraignment Tuesday night, used to work for Child Protective Services, her mom said.
