Esteban Chavez Jr. passed away at age 24.

He worked as a UPS driver in California for over 4 years.

He died one day after his 24th birthday.

He reportedly finished making a delivery last Saturday when temperatures were over 90 degrees.

Apparently, he collapsed in his truck after making a delivery.

The owner didn’t realize the truck was still there until twenty minutes later.

He called the paramedics, but by the time they arrived, it was too late.

His family believes he died of heatstroke, but an official cause of death is still to be determined.

His family passed their GoFundMe goal of $20,000 dollars on Sunday morning.
