The charges stem from September, when Johnson was arrested near Detroit Lakes after Otter Tail County authorities received a report of arson at a wooden bridge that links the west and east sides of Star Lake, not far from Johnson's home.

According to court documents:

Investigators found several 20- and 30-pound propane cylinders under the bridge, and one that appeared to have exploded was floating in the water.

A matchbook was found lying in the road near the bridge.

Witnesses told officers they had suspicions about Johnson starting the fire, including one witness who said Johnson had made comments about blowing up the bridge near his house.

A search of Johnson's house revealed ammunition and a shotgun, according to court documents.
