A mother and her boyfriend charged in the death of a 2-year-old Lincoln County boy have been bound over for trial following their preliminary hearing in the death penalty case and the child's autopsy report has now been finalized and released.

The autopsy ruling from the Office of the Chief Medical Examiner shows Braxton A. Danker died from a subdural hematoma due to a beating, with cause of death listed as homicide.

Braxton, who died May 13, 2018, had significant injuries that were noted during the autopsy, including a subdural hemorrhage, old rib fractures, as well as numerous contusions and abrasions, the report shows.

Lincoln County prosecutors previously filed a Bill of Particulars to have a death penalty option, upon conviction, against the two charged in the child's death.

The toddler’s mother, Judith C. Danker, 19, and her reported boyfriend, Khristian T. Martzall, 27, both face a charge of murder in the first-degree, child abuse.

Charges were filed in May. During a recent preliminary hearing, enough evidence was found for their cases to proceed and both are now set for follow-up arraignments on Jan. 15. 2019.

Pottawatomie/Lincoln County First Assistant District Attorney Adam Panter said this was the worst case of child abuse he’s ever seen, adding that the death penalty is the only true justice for the child.

“Braxton spent his last days of life suffering,” Panter said.

The death penalty request outlines aggravating circumstances, such as the heinous nature of the crime, and gives a jury an option on whether the death penalty is a possible punishment for the defendants, if they are convicted.

The child lived with his mother and her boyfriend in Wellston, Panter said, and the mother was reportedly rushing the child to the closest Emergency Room in Edmond when an ambulance met them en route and transported the child, who died a short time later.

Judith Danker and Martzall both remain jailed while awaiting trial.
