Doyle J. Hundley Jr and Casey R. Layton, of Harbeson, are charged with first-degree murder by abuse, and endangering the welfare of a child by knowingly acting in a manner likely to injure thus causing death.

The mother and father of a Harbeson infant who died after being on life support for five months have been charged with murder

Delaware State Police homicide detectives arrested the parents of Aiden R. Hundley, 8 months, on Dec. 10, said Delaware State Police spokesman Master Cpl. Gary Fournier.

The father was identified as Doyle J. Hundley Jr., 37, and the mother as Casey R. Layton, 28, both of the 18000 block of Harbeson Road. They also are the parents of a two-and-a-half year old boy, Fournier said.

The case began May 23 when 911 dispatchers received a call from Hundley saying Aiden, who then was three months old, had suffered a seizure and was not responsive. Paramedics and emergency medical personnel first took the boy to Beebe Hospital in Lewes before he was flown to A.I. DuPont Children’s Hospital, where he was admitted in critical condition suffering from multiple broken bones and a serious head injury, Fournier said.

An autopsy was conducted after the boy died on Sept. 22, resulting a finding of homicide due to blunt force trauma to the head.

Further investigation showed the infant suffered numerous injuries over the two months he was in the care of his parents, who could offer no plausible explanation for the injuries, Fournier said. Both Hundley and Layton were the boy’s only caretakers, he added.

“The injuries were so severe that they would have been obvious to any caretaker,” Fournier said.

The parents were arrested after police reviewed the case with the Delaware Attorney General’s Office.

Both are charged with first-degree murder by abuse, and endangering the welfare of a child by knowingly acting in a manner likely to injure thus causing death.

Hundley and Layton are being held on $106,000 cash-only bond each.

Aiden’s older brother was placed in the care of the Delaware Department of Services for Children, Youth and their Families and does not appear to have been harmed, Fournier said.
