TACOMA, Wash. —  The Army is taking over prosecution of a Fort Lewis soldier accused of killing two other soldiers in Parkland.

A base spokesman Joe Piek says the Army has a greater interest in the case. He said Ivette Davila is being held Wednesday at the Navy brig at Bangor. She was moved from the Pierce County Jail in Tacoma before prosecutors filed charges.

The 22-year-old from Bakersfield, Calif., is accused of shooting 27-year-old Timothy Miller and his wife, 25-year-old Randi Miller, on Saturday night at their home. Both were medics who had served in Iraq. Investigators have said a possible love triangle may have been the motive for the killings.

Randi Miller's father lives in Laconia, N.H., and Timothy Miller's family lives in Gardnerville, Nev.
