Defendant allegedly sent a ‘manifesto’ in connection with anger over his father’s death some 20 years ago

Tacoma – A 46-year-old resident of Graham, Washington was charged today in U.S. District Court in Tacoma following the investigation into his threats to build a bomb and set it off in a public area, announced Acting U.S. Attorney Teal Luthy Miller. David Michael Eddo was arrested yesterday and made his initial appearance on the criminal complaint charging him with illegal possession of ammunition this afternoon. He is scheduled for a detention hearing on Wednesday June 18, 2025. He remains detained at the Federal Detention Center at SeaTac.

According to the criminal complaint, Eddo is prohibited from possessing firearms or ammuniti0n because of his conviction for drive-by shooting and assault. In that 2019 case, Eddo fired multiple shots into the cab of a semi-truck that was on the I-5 exit ramp to the Port of Tacoma. He was sentenced to 26 months in prison.

In early May 2025, Eddo came to the attention of the FBI for writing a ‘manifesto’ in which he claimed to be building and deploying a bomb to get ‘justice’ for his father who died approximately 20 years ago at the Port of Tacoma. Eddo allegedly names certain people who were involved in litigation over his father’s death as targets in the manifesto.

On June 12, 2025, law enforcement searched Eddo’s Graham home and recovered various items that could be used to make an explosive device including Ammonium Perchlorate also called Potassium Nitrate. Eddo had no license to purchase, use, or store explosives.

Additionally, agents recovered two different types of ammunition. Unlawful possession of ammunition is punishable by up to 15 years in prison.

The charges contained in the criminal complaint are only allegations.  A person is presumed innocent unless and until he or she is proven guilty beyond a reasonable doubt in a court of law.

The FBI is leading the investigation. The case is being prosecuted by Assistant United States Attorney Elyne Vaught.
