BUTTE, Mont. — Officials in southwestern Montana have identified the Idaho woman and two young cousins who were killed in a rollover crash on Interstate 90 near Deer Lodge.

The Montana Highway Patrol says the July 28 crash killed 61-year-old Cynthia Boone of Coeur d’Alene. The crash also killed Boone’s granddaughters — 12-year-old Olivia Tavares of Rexburg and 10-year-old Lexi Minish of Priest River.

The patrol says Boone overcorrected after driving into the median. The crash injured two other children, ages 6 and 2.
