Police are investigating the death of a 1-year-old girl who was found unconscious in her family's Staten Island home Monday morning.
Authorities say they responded to a 911 call at little Bianca Abdul's Moreland Street home around 8 a.m. and found the child unresponsive.
The girl's aunt, who lives next door, told News 4 Tuesday that Bianca's mother found her unconscious inside a playpen. The aunt tried to save her.
"I tried my best to revive the baby," said Linda Fleschner.
"I just know the baby was cold and wasn't breathing," she said. "I tried giving her CPR and the EMTs came and worked on her for an hour."
Sources say Bianca's mother told police the child had hit her head on Friday and was lethargic on Sunday.
She was taken to a hospital, where she was pronounced dead. Police say there were no obvious signs of trauma, but their investigation is ongoing.
The medical examiner will conduct an autopsy to determine how she died.
The family has been the subject of investigations by the city's Administration for Children Services: according to sources familiar with the case, at least three complaints about child abuse were filed between 2015 and 2016.
They said a 12-year-old was removed from the home in the past, but later returned.
Neighbor Nancy Peredo says she's seen police at the home "many times. Many times the police, many times the ambulance, all the time."
Bianca's father had not been around the family for a week because an order of protection had been filed against him by the child's mother, police said. He was taken into custody Tuesday for violating the protection order when he showed up at the home.
