A former police officer has been charged in the death of her daughter after allegedly leaving the three-year-old inside a hot police cruiser. Cassie Barker, 27, says she went inside her boss' house and only expected to be there for a short time, while she left her daughter, Cheyenne Hyer, in the cop car with the windows up and air conditioning running. Barker claims, instead, she fell asleep inside her supervisor's home for five hours. Both Barker and Sgt. Clark Ladner have been fired for the incident.
