When news about the shooting began to spread, everyone in Montana and much of the country mourned the senseless death of Deputy Moore. A section of Highway 287 has since been dedicated in Moore's honor. The Mason Moore Foundation was also created to show love and support for Law Enforcement Agencies in Montana.

The two people responsible for the murder are father and son, Lloyd and Marshall Barrus. After the pair shot Moore, they led law enforcement on a high-speed chase that eventually led to a shootout east of Missoula. Marshall Barrus was killed during the shootout, and his father, Lloyd, was sentenced to life in prison without parole. The tragic incident is one that Montana residents won't soon forget.

A special 2-hour episode of NBC's Dateline is scheduled to air Friday at 8:00 p.m., revealing new details about the night Deputy Moore was murdered. Click here for more information.
