RAMSTEIN AIR BASE, Germany — Autopsy results released by German police indicate the wife of a Ramstein noncommissioned officer suffocated her youngest daughter, stabbed another and then killed herself, the German newspaper Die Rheinpfalz reported.

Chief District Attorney Eberhard Bayer told the newspaper there was no indication of anyone else being involved in the deaths.

Christine Staggs, 39, and her daughters, Vivian Staggs, 12, and Savanna Kjonaas, 3, were found dead July 17 in the woods near Hauptstuhl, about 10 miles west of the base.

They had been missing for three days.

Staggs was the wife of an Air Force master sergeant whose name has not been released.

Savanna’s body showed no external injuries. The autopsy results stated that she “most likely suffocated,” the newspaper reported.

Vivian’s body showed several stab wounds and cuts to the chest and stomach.

Staggs’ cause of death was a “multiple circulatory failure,” which probably resulted from a huge loss of blood, the report said.

Her body, according to the newspaper, had several stabs to the chest and stomach and cuts on her neck and wrist. She also had carbon monoxide poisoning from car exhaust fumes.

Bayer said that the woman had connected a hose from the muffler to the inside of the car, the newspaper reported.
