A Shawnee mother and her boyfriend were formally charged Thursday afternoon with murder in the first degree for the death of 2-year-old Jamie Denise Murdock, court records show.

The child's mother, Whitney D. Breslin, 22, and her boyfriend, Cashe K. Graham, 22, made a court appearance and were formally charged in Pottawatomie County District Court.

Both have been jailed since their arrest earlier this month. Jamie died Sept. 2 at OU Children’s Hospital in Oklahoma City.

Both Breslin and Graham are accused in the first-degree murder count of acting conjointly with each in the death of a child, court records show, which resulted from the willful or malicious injuring, torturing, maiming or using of unreasonable force when causing blunt force trauma to the head and torso of the child.

In the alternative, a charge of murder in the first degree, permitting child abuse also was filed. In that count, they are accused of taking the life of a child by maliciously engaging in enabling child abuse by means of causing, procuring or permitting a willful or malicious act of child abuse and by authorizing or allowing for the care of the child by an individual when the person authorizing or allowing such care knew or should have known that the child would be placed at risk for abuse.

Their next court date is Nov. 21.

Both were arrested by Shawnee police on Sept. 5.

The case began about 11:41 a.m. Sept. 1 when police and medical services were dispatched to a home at 1222 E. Highland for a 911 call involving an unresponsive child, Sgt. Dan Shumaker said. At the time, it was noted the child had head and abdomen injuries.

Jamie was first transported to St. Anthony Shawnee Hospital and later transferred to Children’s Hospital.

As detectives investigated the case, the probe resulted in the mother and her boyfriend being taken into custody.

Arrest affidavits show the child died from non-accidental abusive head trauma that the child could not have caused to herself.
