Dr. Hamilton 911 call: Real Audio | Transcript

The document -- a probable cause affidavit signed by an Oklahoma County District Court judge -- describes some of the evidence that led homicide detectives to believe Hamilton beat and strangled his wife, Susan Hamilton, 55.

Mack Martin, Hamilton's attorney, has said his client is not guilty of the crime. Martin declined to comment Tuesday.

Hamilton, a prominent obstetrician and gynecologist, was charged with first-degree murder. He has been held without bail in the Oklahoma County jail since Feb. 14, the day of the slaying.

Hamilton, 52, called 911 at 11:06 a.m. on Valentine's Day, telling dispatchers that somebody "hurt" his wife, who was "bleeding all over the place." He identified himself as a doctor and said he thought his wife was dead.

When police arrived, Hamilton was wearing bloodstained clothing, but no shoes or necktie. His wife was lying nude on the bathroom floor in a pool of blood. She had suffered blunt- force trauma to her forehead, and a necktie was around her neck.

The doctor told police he performed cardiopulmonary resuscitation on his wife, then called for help when she did not respond, the affidavit says. He resumed CPR after completing the call. Hamilton was taken to police headquarters for questioning.

Police described his demeanor as inappropriate.

"Dr. Hamilton appeared to be acting and not truly concerned for the victim," the document said. "Dr. Hamilton did not act as a person who often comes in contact with emergency situations."

From talking to those who knew the couple, police learned that Susan Hamilton recently had accused her husband of having an affair, which led to "heated" arguments, the affidavit says.

The condition of the crime scene also made investigators suspicious, the affidavit said.

"Although the house was reported unlocked and opened by Dr. Hamilton, there was no evidence of escape by a bloody suspect," the affidavit said. "The crime scene was extremely bloody, and the suspect could not have left the residence without leaving some evidence of a blood trail."

Hamilton was arrested about six hours after he called for help.

A separate affidavit made available Monday lists physical evidence -- including clothing, a bloody wash rag, Valentine's Day cards, syringes and thousands of dollars in cash -- that were taken from Hamilton's house, automobile and locker in the men's surgical dressing room at Mercy Health Center.
