Some media outlets are assuming the woman arrested is the baby's mother. Like here on WNYW, you can see the text says "mother of abandoned girl caught."
Other outlets were a little more careful, never calling the baby the woman's child, like here in The New York Times.
WCBS reports the woman has actually admitted to being the child's mother, but then still labeled her "woman" in the video.
After she got off the subway, someone reportedly recognized her from photos released by law enforcement and called police. Investigators then took the woman in for questioning.
The child was thought to be around seven months old. And while the child would be too old for New York's Safe Haven law, the state does have one, meaning, a baby up to 30 days old can be left with "any responsible person at a suitable location in New York." These laws decriminalize giving up a child.
Multiple reports say a bystander saw the stroller and stayed with the child for about 20 minutes before deciding to call police. The child is in the care of the Administration for Children's Services.
