Lawson Whitaker died after being left in this truck for eight hours. He dropped his daughter off at school, but forgot to drop his son off at daycare, Smalls said. He ran errands around town, and saw his son in the backseat of the Chevrolet truck in the afternoon, when he was back home. Whitaker, who is a firefighter with the nearby Hillsborough County Fire Department, performed CPR on his son before medical officials arrived, Sheriff Bob Gualtieri told reporters. The boy had an "extremely high body temperature" and was transported to Mease Countryside Hospital, where he was pronounced dead, the sheriff said. "It was obvious that he had been dead for a while," Gualtieri said. After leaving a child in a car, 'that pain ... never goes away' The sheriff said the boy was in the truck from about 8:30 a.m. to 4:30 p.m., when Whitaker returned from a trip to the supermarket. "It was evident that he didn't realize that the child was in the backseat until he arrived home from Publix," Gualtieri said. "He was taking the groceries out of the front passenger seat and immediately dropped the bags -- there are groceries all over the driveway -- and then went and took the child out of the car seat." The boy's car seat was behind the driver's seat, the sheriff said. "As you can imagine, he was extremely upset -- visibly upset," he said. The boy's mother was at the hospital Friday evening with other family members, he added. and yes i know we need this..
