UPS driver dies days after working in searing Texas heat

A Texas UPS driver fell ill while working during a scorching heat wave and later died.

According to a statement from UPS, Christopher Begley, 57, died this week shortly after becoming sick earlier this month while on his route in North Texas, where the high temperature at the time topped 100 degrees. The exact cause of death has yet to be determined, and authorities are investigating,

"We train our people to recognize the symptoms of heat stress, and we respond immediately to any request for help," the delivery giant told CBS MoneyWatch. "We are cooperating with the authorities as they continue to investigate the cause of death."
