FARMINGTON — Davis County prosecutors will file a negligent homicide charge against the mother of a 5-month-old baby who died in a sweltering hot car in Layton.

"Based upon what we know about all of the factual circumstances surrounding this situation, we felt like this was the fairest, most just and equitable decision," Davis County Attorney Troy Rawlings told the Deseret News shortly after meeting with his staff to discuss the case on Wednesday.

The charge expected to be filed today against Kamilyn Hadley is a class A misdemeanor. Rawlings declined to go into details about the case.

Police said Daniel Scott Hadley was left in a car while his mother was inside a Layton home visiting a friend. When she came out a couple of hours later, police said she discovered the boy unresponsive. Temperatures in Layton were about 89 degrees on June 17. Inside the car, experts said it would have reached approximately 120 degrees.

Police said his mother tried to cool him off and eventually drove him to Davis Hospital. He died several days later.

Since Hadley's death, the Davis County Attorney's Office has received numerous calls about charging Hadley over the death of her son. Some demanded "justice for the baby," while others said the mother has suffered enough, Rawlings said.

"Our decision was not based upon public opinion at all," he said.

Rawlings said he had already been in touch with an attorney for Hadley and hoped they would be able to reach a resolution soon.

"We are engaging in continued discussions," he said.

Hadley will not be arrested but will soon be issued a summons to appear in 2nd District Court. She faces up to a year in jail or probation if convicted of the charge.
