A Pokémon Go player made an unexpected and unfortunate discovery while playing the augmented reality Pokémon game today. 19-year-old Shayla Wiggins of Riverton, Wyoming says she found the body of an unidentified man while searching for Pokémon, according to a report from County 10.

Wiggins says she found the body in the Big Wind River. She says she was "trying to get a Pokémon from a natural water resource" and discovered the body.

The Fremont County Sherriff’s Office said in a press release that the man’s death appeared to be accidental and possibly the result of a drowning. There is no evidence at this time that indicates foul play, Fremont County undersherriff Ryan D. Lee said in a statement. The investigation is ongoing.

Pokémon Go launched on Android and iOS devices earlier this week. The game, which was developed by Ingress creator Niantic Labs and The Pokémon Company, tasks players with visiting real-world locations to discover and capture Pokémon.

The app warns players to "be alert at all times" and stay aware of their surroundings while playing.

Pokémon Go's popularity with mobile game players has lead some government institutions to urge caution, warning fans to stay away from police stations and to refrain from playing the game while driving.
