Neil White has been arrested on a murder charge. She saw that White had bloody cuts on his wrists.
Told the nanny, 'I went upstairs, and I kept calling, "Neil?" Describing Gabrielle as "beautiful", she said the seven-year-old was " the light of their lives".
Gazzola said the blood found in the house is believed to be Neil White's.
Her cause of death appears to be asphyxia by suffocation, but the medical examiner will determine the official cause, police said.
Police did not say what caused the young girl's death, but say it is being investigated as suspicious. "I want to see her!'"
The couple were living in separate residences and shared custody of their daughter.
This story has been corrected to show the girl's name was Gabrielle, not Gabriele.
The mother's family said Wednesday it's "broken and devastated" Gabrielle is gone.
"He lost himself and in that deep dark place he acted out".
He added that there's "no logic or reason" for this frightful crime. "It pushes the boundaries of reason that a father could kill his daughter", Rev. Richardson said.
At a press conference prior to the arraignment, New Rochelle Mayor Noam Bramson said the day was "an exceptionally painful day for New Rochelle". "Our entire community mourns this tragic event and is united in offering thoughts and prayers to Gabrielle's mother and to all who knew and loved Gabrielle".
Announcing the ruling on Wednesday, New Rochelle City Judge Anthony Carbone ordered to have Neil White locked up and issued two orders of protection - for Michelle Hord-White and for another person, whose name hasn't been disclosed to the media, but it's presumably the babysitter who was the first person to arrive to the scene. He is due back in court on June 15.
