Here’s How Hot It Is Inside a Mail Truck

It was a day of blistering heat in Southern California, and now the family of mail carrier Peggy Frank, 63, wants to know whether she was killed by extreme temperatures while on the job. Frank was found dead in her mail truck in Los Angeles earlier this month. The temperature outside was a record 117 degrees. “Our thoughts and prayers are with the employee's family at this difficult time,” the U.S. Postal Service told Inside Edition. “The unfortunate incident involving this employee remains under investigation.”
