NORTH SYRACUSE, N.Y. -- Sirens and police activity woke Peggy Gazlay up early Friday morning. When she walked out of her Carlton Drive home the scene was chaotic.
"The street was filled with the fire department and police officers. Firemen had brought out a little girl, put her on a stretcher and was doing CPR on her," said Peggy Gazlay, a neighbor.
Police say that little girl is 6-year-old Gabriella Collins.
The Onondaga Sheriff's office said just after 6:30 Friday morning her father, Glenn Collins arrived home and found her 14-year-old brother, Jaden Collins unconscious.
They were transported to the hospital where Gabriella was pronounced dead and her brother is in critical condition. Authorities are investigating what led to this but they are focusing their attention on one possibility.
"Carbon Monoxide. The Onondaga County Medical Examiner's office is involved in this investigation at this time," said Dan Brogan, Onondaga County Sheriff's Captain.
Brogan said the home, 106 Carlton Drive, did not have power but its unclear why or what was being used to provide power.
Meanwhile Gazlay said she didn't know the family well but said they were friendly and remembers Glenn playing basketball with Jaden, and Gabriella riding her bike outside.
"It's absolutely eating me up inside to know that a little girl is deceased because of the situation it's very tragic, tragic," said Grazlay.
Detectives will remove evidence from the scene, and then the codes department will step in.
Investigators say codes had been involved previously at the home. They are awaiting the medical examiners report to determine the cause of death.
