Law enforcement officers are searching for two men who reportedly robbed a Missoula casino, took a family hostage and fired shots at pursuing officers before finally freeing the uninjured hostages at separate locations.

Missoula County Sheriff T.J. McDermott said the men robbed Deano's Casino at about 3:30 a.m. Friday, carjacked a family from Lake Stevens, Washington, and sped through downtown Missoula.

A 12-year-old boy, a 14-year-old girl and their grandmother were released in Missoula. The family's vehicle and the children's parents were located at about 5:30 a.m. near Evaro Hill, northwest of Missoula.

McDermott says the suspects were on the phone arranging for someone to pick them up before they fled the family's vehicle on foot.

The suspects are a black man and a white man, both about 5 feet, 7 inches tall and in their early 20s.
