A mother rushing home to prepare for a birthday party in northeast Harris County left her 5-year-old son in a vehicle for two to three hours before realizing he was in there, authorities said on Monday. The child died as a result, according to Harris County Sheriff Ed Gonzalez. The investigation into the hot car death got underway on a cul-de-sac about 3:19 p.m. Earlier, the mother and her two children - the 5-year-old victim and an 8-year-old daughter whose birthday party was being thrown - went to a store as part of the celebration preparations, Gonzalez said. #hotcardeath #texas #childies READ MORE: https://6abc.com/texas-hot-car-death-homicide-investigation-child-died/11982034/
