A Fort Lewis soldier has been arrested for investigation of killing a military couple and abducting their 7-month-old girl, sheriff's deputies said.
The 22-year-old woman was booked into the county jail Sunday night for investigation of two counts of first-degree murder and one count of kidnapping, Pierce County Sheriff's spokesman Ed Troyer said.
The woman is an active-duty soldier with I Corps at the Army base south of Tacoma and a member of the honor guard, Troyer said.
Acting on information from the Army, deputies went to a home south of Tacoma on Sunday and found a man and a woman dead, Troyer said.
The county Medical Examiner's Office did not immediately release the names of the victims, a 25-year-old man and 27-year-old woman. Both were in the Army, but their relationship to the arrested woman was not immediately known.
The victims appeared to have died from gunshot wounds, thought to have been inflicted Saturday, deputies said.
The baby belonging to the couple was missing from the home and was found with the Fort Lewis soldier, authorities said. The baby was not harmed and was in the care of the state's Child Protective Services agency.
