A young man was shot in the chest in what appears to be an accidental firearm discharge on Sunday in Lockwood. Yellowstone County Sheriff Deputies responded to a house party on Old Hardin Road shortly before 8 p.m. A male brandished a firearm, and one round discharged, striking another in the chest. The victim was transported to St. Vincent Hospital and is listed in critical condition. No arrests were made, but those involved could face charges.
