Officials ID 'Person of Interest' in ND Slayings A man who has been called a "person of interest" in the slayings of a northwestern North Dakota woman and three of her grandchildren has been identified. Mountrail County Sheriff Ken Halvorson says 21-year-old Kalcie Eagle, of New Town, was the man who stabbed himself to death in front of a deputy and a highway patrolman Sunday night in Parshall. Halvorson says authorities are still trying to determine what, if any, role Eagle played in the shooting deaths Sunday of 64-year-old Martha Johnson and three of her grandchildren on the Fort Berthold reservation. Halvorson also says that Eagle lived about a block away from the Johnson home. FBI spokesman Kyle Loven declined comment, citing the ongoing investigation.
