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

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

Both have been jailed in the Pottawatomie County Public Safety Center 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 Jamie 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 appearance is scheduled 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. 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, where she died the afternoon of Sept. 2.

As detectives investigated the case, the probe resulted in police obtaining information from doctors.

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

“The injuries are from a traumatic brain injury with herniation. There is swelling to the back of Jamie's head on the left side,” it reads. “Jamie also had external bruising and retinal hemorrhages. The injuries are consistent with abusive head trauma with no history of accidental injury.”

The affidavit shows Jamie also had trauma to her liver, but the doctor noted that would not have resulted in her death. The child also tested positive for marijuana in her system.

When police questioned Breslin and Graham, they denied smoking marijuana around the child but admitted that Graham kept marijuana in a tool box and only smoked it outside, but never around the children, the court document reads.

Based on their initial statements to police, the affidavit shows that Breslin went to the grocery store about 10 a.m. that morning. At about 10:30 a.m., the child got up and went to the bathroom and said, “Hey Cashe,” and then went back to her bed. About 11 a.m., Breslin came home and unpacked groceries while Graham brought in some bottled water. From there, the affidavits indicate Breslin made coffee and she and Graham went on the back porch to smoke a cigarette.

When Breslin went in to wake up Jamie, she noticed she was gasping for air, the affidavit reads, and told Graham to call 911. Jamie stopped breathing and Breslin was able to get her to breathe again, the document reads.

When both agreed to the interview with police at the hospital, both stated they didn't know how the child received her injuries, the court records reads. Police arrested the pair on Sept. 5.

The child’s death has brought up many questions about prior issues. Detective Jason Crouch has confirmed DHS was investigating an incident that allegedly occurred on Aug. 4, so DHS was reportedly involved with this child.

The News-Star, earlier this month, contacted DHS to formally request a summary of DHS records involving this child, with DHS reporting that request could take up to 45 days.
