Law enforcement officers from multiple agencies are on the lookout for 26 year-old Brandon Conrad Meisner, wanted for a suspicious death in Great Falls, who then allegedly carjacked a vehicle and fled to Helena.

Authorities say that Meisner then drove to the Hauser Dam area and the Black Sandy State Park, and that he considered armed and dangerous.

Lewis and Clark Sheriff Leo Dutton said in a news release that Meisner is armed with a ,45 caliber handgun. He is described as being about a white male, 6'3" tall, weighing about 200 pounds and is bald.

Helena police are advising residents in the area to mlock their doors and vehicles and report any contact with Meisner to 9-1-1 immediately.
