Three years after the Jan. 6 U.S. Capitol riot, the FBI is still seeking the suspect who planted a pipe bomb near the headquarters of the Republican National Committee and the Democratic National Committee on the eve of the attack. 

The pipe bombs, which had an hour-long kitchen timer as a detonator, were viable, but didn’t detonate and no one was hurt, the FBI said. 

“Over the past three years, a dedicated team of FBI agents, analysts, data scientists, and law enforcement partners has worked thousands of hours conducting interviews, reviewing physical and digital evidence, and assessing tips from the public about who may have placed pipe bombs on Capitol Hill,” David Sundberg, assistant director in charge of the FBI Washington Field Office, said Thursday.

He added, “The tips we have received so far from the American people have helped us advance the investigation, and we ask the public to continue to assist us by taking a fresh look at our ‘Seeking Information’ webpage, which includes images and video of the suspect, the suspect’s backpack, the suspect’s shoes, the explosive devices, and a map of the route the suspect walked the night the pipe bombs were placed.

He said the agency’s $500,000 reward for information leading to an arrest remains in effect and, “We urge anyone who may have previously hesitated to come forward or who may not have realized they had important information.”

Last year, Steven D’Antuono, former assistant director in charge of the FBI’s Washington Field Office, told the House Judiciary Committee that a search of cellphone-pinging data in the area was incomplete because some of it was “corrupted by one of the providers,” the Washington Examiner reported. 

He added, “To my knowledge, it wasn’t corrupted [intentionally], you know, but that could have been good information that we don’t have, right. So that is painful for us not to have that. So we looked at everything.”
