Brian Patrick O'Callaghan, 36, of Damascus, Md., has been charged with first-degree murder and child abuse in the beating death of his three-year-old adopted son, Hyunsu O'Callaghan. O'Callaghan adopted Hyunsu from Korea and brought the child home to the U.S. in Oct. 2013.

UPI reported on Feb. 19 that O'Callaghan was the chief of the National Security Agency's Korea division.

On Feb. 2, O'Callaghan took his severely injured son to the Children’s National Medical Center in Washington. The child was unresponsive at the time. Officials at the hospital contacted authorities immediately upon realizing that the child’s injuries weren't accidental.

O'Callaghan was watching his son while the boy’s mom, Jennifer O'Callaghan, was out of town for a few days. The father said that Hyunsu hurt himself after falling in the shower on Jan. 31.

The next day, O’Callaghan said he put the boy down for a nap, but when he went to check on him, the child had mucus coming from his nose and began vomiting after he was picked up, police said. ~ CBS News DC

While at the hospital, doctors became immediately concerned over Hyunsu’s “internal bleeding in the brain and hemorrhaging in the eyes.” The child also suffered skull fractures, indicating that his injuries were from a beating – not from falling in the shower. Doctors also confirmed multiple contusions on the boy’s body.

Hyunsu died the next day on Feb. 3, “of multiple blunt impact injuries, which O’Callaghan could not explain or account for, according to police charging documents.”

O'Callaghan was arrested by Montgomery County police on Feb. 16 and is being held without bond.

Prosecutors in Montgomery County are convinced that Hyunsu’s death was the result of “cold-blooded murder.”

'An absolutely horrific crime on an absolutely innocent young victim,' said Assistant State’s Attorney Donna Fenton, listing injuries to the boy’s head, neck and back.

'Basically this child was beaten to death from head to toe.'

O'Callaghan is also a decorated Iraq War veteran who was awarded the Marine Corps Achievement Medal. He was involved in the battle that helped rescue captured soldier Jessica Lynch, according to The Daily Mail.

O'Callaghan's wife, Jennifer, said that her husband couldn't have murdered Hyunsu, and that her son’s death must have been a tragic accident.
