FARMINGTON — A negligent homicide charge has been filed against the mother of a 5-month-old Clearfield boy who died after being left in a sweltering hot car.

Kamilyn Hadley, 31, was charged Thursday afternoon in 2nd District Court with a class A misdemeanor charge in connection with the death of her son, Daniel Scott Hadley.

"On June 17, 2008, defendant left her child in a car unattended with the windows rolled up for a period of approximately two hours," Layton police detective Glen Fullmer wrote in a probable cause statement. "Due to the heating of the car, the child later died."

Police said the baby was in Hadley's car when she went to visit a friend in Layton. She came out a couple of hours later and found the boy unresponsive. After trying to cool him down, she eventually drove him to Davis Hospital. He died a few days later.

Temperatures in Layton were about 89 degrees on June 17. Inside the car, police believe it would have been approximately 120 degrees.

Hadley is expected to be issued a summons to appear in court. Davis County Attorney Troy Rawlings said he is working with her attorney to reach a resolution in the case and has no plans to recommend jail time if she is convicted. A class A misdemeanor negligent homicide charge carries with it the possibility of up to a year in jail or probation.

Daniel Hadley's death is the second hot car-related death in Utah this year. In April, 18-month-old Myles Gailey died after being accidentally left in a car in Kearns. Police said his mother was unloading groceries and forgot her child.

The Salt Lake District Attorney's Office declined to pursue charges in that case.
