Cops tell the New York Daily News that the woman, identified as Latisha Fisher, brought a two-year-old, Gabriel Ortiz, into a bathroom at Five Boro Burger in midtown around 3 p.m. Monday. It's not clear how they were related.
When a woman walked into the bathroom and saw the mother holding her hand over the baby's mouth, Fisher said "I put my hand over his mouth to put him to sleep," according to cops.
At some point the woman locked herself in the bathroom, according to police sources.
When workers forced open the door, the child was unconscious and foaming at the mouth, according to the sources.
Ortiz was reportedly pronounced dead at Bellevue hospital.
