Another witness saw a UPS driver who made multiple rescues before he collapsed and needed the attention of first responders.

“I saw the UPS driver take the older lady and walk her across the street, as well as two Irish men,” Raul Garcia said. “The UPS driver collapsed to the floor because he was the first one to enter the home and help the older lady out, and he was getting first responder help right away.”
