Police in Nichols Hills said a doctor was arrested on a murder complaint in the death of his 9-year-old son.
Police Chief Richard Mask said officers were called to the Oklahoma City suburb home just before 4 a.m. Monday and found Tommy Wolf wounded.
The police chief said the first 911 call came from a neighbor where Wolf's wife, Mary , went seeking help.
He said two more calls were made from the Wolf home, apparently by Mary Wolf.
Mary Wolf is hospitalized with defensive wounds that authorities said were not life threatening.
Mask said 51-year-old Stephen Wolf is being held without bond in the Oklahoma County jail.
