A World War I gas mask stolen nearly 100 years ago from the Wyoming State Capitol is back home after ending up in a South Dakota pawn shop.
The Wyoming State Museum announced its return Wednesday.
The mask and other artifacts were brought back to the United States by Sgt. Robert Pennewill after the war. The collection was purchased in 1919 by entrepreneur William Coe, who donated it to Wyoming.
Many of the items were stolen from an exhibit at the Capitol in 1920. Earlier this year, the museum received a tip that a mask being sold online by the Presidential Pawn shop in Rapid City, South Dakota looked like the one taken from Wyoming. The shop donated it to the state.
