A Virginia mom thought her 17-month-old son was safe an at daycare on Wednesday, until she got a call from the childcare center around 12:30 p.m.

Her husband had never dropped little Riaan Gondesi off, NBC 10 reports.

The father, who has not been identified by police, was at work at the Capital One West Creek Campus when he got a frantic call from his wife. 

Goochland Sheriff James L. Agnew told Richmond Times-Dispatch that the father quickly went to check his car, which had been parked on the top level of a parking deck:

“The mother called the father. He ran out to the car and discovered his son.”

Police estimate that the car was about 120 degrees when the father found Riaan.

There was no shade to shelter the vehicle from the sun, NBC 12 reports. 

Both parents contacted police and the infant was rushed to St. Mary’s Hospital. He was declared dead about an hour later. 

The father told police that he thought he'd dropped off his son at daycare before heading to work.

A medical examiner has yet to confirm the cause of death, and police said the investigation is still underway. 

In the meantime, no charges have been filed against the father. 

Capital One released the following statement about the incident:

This is a tragic situation and every parent's worst nightmare. Our deepest thoughts and concerns are with the family.

Riaan's death marks the 31st child hot car death nationwide this year. 

A similar death occurred in Indiana late last month, when a mother forgot her 3-month-old in the backseat and went to work, Dearly reported.

According to NBC 10, a safety organization said that the U.S. is on pace to have the more child hot car deaths this year than ever.

Goochland County was under a heat advisory at the time the 17-month-old died.
