A federal grand jury indicted a Napa man for threatening to kill a senior government official in Washington, D.C., the U.S. Attorney’s Office announced.
Haddow Mills, 64, made his initial appearance in federal court in San Francisco Thursday, March 5, prosecutors said in a news release.
The indictment, filed Jan. 28 and unsealed Thursday, alleges that on Sept. 25, 2025, Mills sent an email threatening to murder the government official, who is identified in court documents only as the “victim.”
In the email, Mills allegedly wrote, “I will hunt [the Victim] down and kill him,” federal prosecutors said.
Prosecutors said the government official serves in a U.S. Senate-confirmed role, but they did not disclose the official’s name in the indictment. A spokesperson for the U.S. Attorney’s Office declined to comment when asked about the victim’s identity.
According to the indictment, in the months leading up to the threat against the official, Mills sent dozens of harassing and threatening emails to the official’s former spouse. In one message, Mills allegedly said, “I still am hunting down [Victim’s first name]. He is a dead man walking.” Authorities allege Mills sent other emails containing threats against the official, the former spouse and their children.
Mills was released on bond following his initial court appearance. He is scheduled to return to U.S. District Court in San Francisco on May 21 for a status conference.
If convicted, Mills faces up to five years in prison and a $250,000 fine for transmitting an interstate communication containing a threat to kidnap or injure another person.
