Now, police are looking for a killer as the baby recovers from dehydration.
A lone police officer guards the door of apartment 3H at 312 Main Street in White Plains.
Saturday afternoon cops responded to a call of an "unresponsive woman."
They found Sabrina Durrah dead on the floor, the 4-month old baby girl next to her was alive, but dehydrated.
"The baby was lethargic. The baby was scooped up by the officers immediately and taken to the hospital immediately to be checked and from what I understand was treated for dehydration. The baby now is fine," said Commissioner David Chong, White Plains Dept. of Public Safety.
Commissioner Chong would not say how or even when the 35-year-old mother died.
One neighbor heard the baby crying on Friday.
"We were outside. Me and my son were like, oh, the baby is crying. The other person said, 'it's not my baby,' because we had two new births in the building," said Joyce Eybers, a neighbor.
Another neighbor from across the hall did not want to be identified.
"It's too much for me right now. It's too much. It's too much, it shakes me up a lot," the neighbor said.
Management told Eyewitness News the apartment building has a state of the art video surveillance system, adding, investigators took the hard disk to examine it for clues.
Police would not say if the cameras recorded a potential suspect.
"They probably know who it is because there are cameras. I mean every exit and entrance in this building has cameras," Eybers said.
