While a Shawnee mother and her boyfriend remain jailed on a murder complaint for the death of her 2-year-old child, police on Wednesday confirmed that DHS was involved in a matter with the child on Aug. 4 and that the toddler, who died Saturday, also had marijuana in her system.

While a Shawnee mother and her boyfriend remain jailed on a murder complaint for the death of her 2-year-old child, police on Wednesday confirmed that DHS was involved in a matter with the child on Aug. 4 and that the toddler, who died Saturday, also had marijuana in her system.

Jamie Murdock, 2, died at OU Children's Hospital in Oklahoma City, police said.

The child's mother, Whitney Breslin, 22, and her boyfriend, Cashe Graham, 22, are currently jailed in the Pottawatomie County Public Safety Center on first-degree murder complaints; formal charges have not been filed.

Both were arrested Tuesday by Shawnee police.

The case began about 11:41 a.m. Friday 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 on Tuesday.

Detective Jason Crouch said doctors have indicated cause of death was bleeding and swelling of the child's brain, although an official cause of death is still awaited from the Office of the Chief Medical Examiner.

Eddie Johnson, a spokesman for the Medical Examiner's office, said an autopsy has been performed on the child, but the “cause and manner of death is currently pending further studies.”

Crouch said the mother and boyfriend have acknowledged the child's injuries and to being the only two people in the home, but Crouch said they haven't admitted any involvement in the child's injuries. The detective, who said the 911 call was placed about 11:41 a.m., believes the injuries occurred within about an hour's timeframe of that phone call.

In addition to her physical injuries, Jamie also tested positive for having marijuana in her system, Crouch said, likely from ingesting it. The suspects have admitted to using marijuana, he added.

The child's death also brings up many questions about any prior issues. On Wednesday, Crouch confirmed the girl suffered two previous injuries that were reported to a doctor or emergency room, and there was a report filed for one of those circumstances.

In that instance, which occurred Aug. 4, Crouch said DHS was called to investigate the matter further.

Crouch, who said DHS and SPD are working together in this investigation, said Detective Ronnie Wilson is the lead investigator on the case.

DHS officials on Wednesday said the case is still in the early stages of the investigation, but the News-Star has formally requested a summary of records from DHS once they become available.
