A Phoenix toddler died in the back seat of a hot car, trying in vain to free himself after his drunken father left him there and went inside the house to sleep it off, authorities said Tuesday. <br /> <br />James Koryor, 41, was arrested and charged with manslaughter and child abuse, police said. <br /> <br />"It was an absolutely horrific death," Phoenix Police Sgt. Trent Crump said Tuesday, KTVK-TV reported. <br /> <br />There were no car seats inside the vehicle, and the boy tried desperately to get out, Crump said. It was not clear whether the doors were locked. <br /> <br />The dad was supposed to take his 2-year-old boy, along with his 5-year-old son, to get haircuts. Instead, he drove to a liquor store, bought a bottle of gin and drank it before driving home at about 2 p.m., police said. <br /> <br />Koryor went inside and fell asleep. The 5-year-old somehow managed to get out of the car, but the toddler was left behind with the windows up as high temperatures soared past 90. <br /> <br />The interior of the car was damaged from the toddler's attempts to get out, Crump said. <br /> <br />The mother was inside the home, studying. She discovered her son's body about 4 p.m., when she went out to drive to class. Neighbors said they heard weeping and wailing from the family's driveway. <br /> <br />Officers initially said there was confusion among family members about who was watching the children. Koryor later admitted to investigators that he had been drinking heavily, police said.
