A Staten Island mother accused of dumping her newborn in the garbage has now been charged with murder, as investigators believe the baby was alive before being put in the trash.

Nausheen Rahman, 28, was charged on Sunday with murder and concealment of a corpse after an investigation stemming from officials’ discovery of an unclothed child in a garbage bag outside her New Springville condo on Saturday, the New York Daily News reported.

Rahman originally went to Staten Island University Hospital on Friday, telling medical staff that she had given birth at home then disposed of the newborn, investigators said to NBC.

Tests were underway to determine exactly how the child had died, with sources telling the Daily News that oxygen was found in the lungs, indicating that the baby had been born alive before being dumped.

Rahman admitted to giving birth, but she said the baby died before she put the body in the trash and headed to the hospital, the Daily News added.

Rahman, now charged with second-degree murder, has been living at that condominium in Staten Island with her family for the past several years, NBC reported.
