NSA official charged with beating adopted son, 3, to death
Former combat Marine who became head of the NSA's Korea division faces first-degree murder charge after alleged attack at Maryland home

A United States intelligence official has been charged with beating his adopted three-year-old Korean son to death.
Brian O'Callaghan, 36, a former Marine, is said to have repeatedly struck the child so hard he died two days later.
It was a terrible tragedy … His family know he is incapable of the crimes
Assistant State's Attorney Donna Fenton listed injuries to the boy's head and back as O'Callaghan was charged with first-degree murder and child abuse.
"It was an absolutely horrific crime on an absolutely innocent young victim," Fenton said at a hearing at Montgomery County District Court in Maryland.
"Basically this child was beaten to death from head to toe."
But O'Callaghan's lawyer, Steven McCool, told the court: "This was a terrible, terrible tragedy and not a crime."
