A 15-month-old California infant is dead after overheating inside a vehicle Sunday in Alta Sierra.

According to the Nevada County Sheriff’s Office, first responders arrived Sunday afternoon at around 4:54 p.m. to a driveway off of Ragan Way. They found the infant unresponsive inside the vehicle.

Despite life-saving measures, the child passed away. According to The Union, the victim’s name is being withheld at this time, per the sheriff’s office request.

“This is a very, very sad situation for all involved, for the family and for the first responders that tried to administer life saving measures,” NCSO Administrative Analyst Ashley Quadros said, according to the outlet.

So far, no charges have been filed. Officials are waiting for autopsy results.

“This is the 3rd Pediatric Vehicular Heatstroke death in California this year and the 20th nationwide. Last year, on the 4th of August, there were 21 PVH tragedies,” Jan Null, CCM, Adjunct Professor of Meteorology at San Jose State University told CrimeOnline in an emailed statement.
