Three Indicted on Federal Charges after Pipe Bombs Were Found in Traffic Stop

ROCK SPRINGS — Three Rock Springs residents were indicted last week on a federal charge of possessing destructive devices containing hazardous and explosive material. The charges came after two pipe bombs were found in a vehicle the Rock Springs Police Department (RSPD) discovered during a traffic stop back in February.

The RSPD and the Federal Bureau of Investigation (FBI) are continuing to investigate the discovery of two pipe bombs after a traffic stop that occurred on February 14, 2021, in the 1000 block of Walnut Street.

In March 2021, detectives and FBI agents located two additional pipe bombs totaling four confirmed pipe bombs in Rock Springs, Wyoming, associated with this investigation. All the pipe bombs were safely disarmed by the Sweetwater County Bomb Squad.

The suspects, identified as Spencer Cottrell and Bryan Foster, were arrested for felony possession, manufacture, transportation, and sale of explosives with intent to unlawfully endanger under Wyoming State Statute 6-3-111(b).

Additional collaboration between RSPD and the FBI resulted in federal charges against three Rock Springs defendants.



FBI Denver is grateful for the opportunity to have assisted the Rock Springs Police Department in investigating this serious threat,” said FBI Denver SAC Michael Schneider. “An important part of our Mission is assisting our local law enforcement partners to protect our communities. We continue to encourage anyone who observes a friend, family member, or acquaintance with dangerous weapons or materials to report them to their local law enforcement or the FBI.”

On May 19, 2021, a Federal Grand Jury, held in Casper, Wyoming, indicted Bryan Foster, Spencer Cottrell, and Gage Mercer for possessing destructive devices containing hazardous and explosive material in violation of Title 26 United States Code Sections 5845(a)(8) and 5845(f)(1)(A).

All parties are presumed innocent until proven guilty.
