A Washington state man accused of making more than 20 swatting calls across the U.S. and in Canada, leading to law enforcement responses to his false reports of bombings, shootings and other crimes, pleaded guilty.

Ashton Garcia, 21, pleaded guilty Thursday in U.S. District Court in Tacoma to two counts of extortion and two counts of threats and hoaxes regarding explosives, U.S. Attorney Tessa M. Gorman said in a news release. Garcia was initially charged with 10 felony counts.

Garcia placed the calls to agencies in Washington state, California, Georgia, Illinois, Kentucky, Michigan, Minnesota, New Jersey, Ohio, Pennsylvania and Colorado, as well as Edmonton, in Alberta, Canada.

According to federal prosecutors, Garcia used voice-over-internet technology to hide his identity during the calls he made in 2022 and 2023. He also called on others to listen as he broadcast the calls on the social media platform Discord.

There have been several swatting incidents targeting Republican and Democrat public officials since Christmas, including GOP presidential candidate Nikki Haley, Sen. Rick Scott, R-Fla., Reps. Brandon Williams, R-N.Y., and Marjorie Taylor Greene, R-Ga., Boston Democrat mayor Michelle Wu and Maine Democrat Secretary of State Shenna Bellows.

The indictment does not disclose how investigators identified Garcia as a suspect in the swatting calls. 

Prosecutors recommend that Garcia serve four years in prison as part of his plea agreement. His sentencing is scheduled for April.

Garcia remains in custody at the Federal Detention Center at SeaTac, Washington.
