A 7-month-old boy left in a hot car in northeast Phoenix has died. The baby has been identified as Zane Endress. Phoenix police said he was in the care of his grandparents at the time. No arrests have been made. The car was parked in a residential neighborhood near 44th Street and Greenway. Police believe the family may have been returning from work, parked their car, and possibly forgot the baby was still inside.
