A preliminary investigation into the death of a 2-year-old girl in New Jersey found that she was indeed left unattended in a vehicle parked in a Franklin Township driveway.
Early reports suggested the toddler could have been left unattended in the car for as many as seven hours on a humid day in which temperatures peaked in the high 80s.
Police, however, say it's unclear how long the child was in the car or who may have been responsible for leaving her behind.
The family's name has not been released and an autopsy is expected to be conducted soon.
No charges have yet been filed.
Officers responded just before 2:30 p.m. to a call about a child in cardiac arrest at a home on Summerall Road. A neighbor, who is a member of a local fire department, was performing CPR on the child.
The girl was unresponsive and died at the scene.
Neighbors told NBC New York that it appeared the parents did not realize the child had been left in the car. They recalled hearing the parents scream in anguish while talking to police.
The child's mother was reportedly taken away in an ambulance after collapsing on her front lawn.
Including Tuesday's incident, there have been 22 hot car deaths in the U.S. this year, according to Kids and Car Safety.
Anyone with information about the incident is asked to call the Somerset County Prosecutor's Office Major Crimes Unit at 908 - 231 - 7100 or the Franklin Township Police Department at 732 873 5533.
