The suspect who planted pipe bombs on Capitol Hill before the Jan. 6 riot still hasn't been identified 4 months later: police chief

• The suspect who planted two pipe bombs before the Jan. 6 Capitol insurrection has still not been identified.
• Metropolitan Police Chief Robert Contee told a House panel the bomber remains at large.
• The bombs were never detonated and were discovered shortly before rioters stormed the Capitol.

The suspect who planted two pipe bombs on Capitol Hill before the January 6 insurrection hasn't been identified, Metropolitan Police Chief Robert Contee said at a US House panel on Wednesday, according to The Associated Press.

The pipe bombs were planted outside separate headquarters for the Republican and Democrat national parties on January 5, but the bombs never detonated.

They weren't discovered until the next day, shortly before rioters in support of former President Donald Trump stormed the Capitol.

At the Congressional panel examining the federal response to the insurrection, Contee said investigators believe the suspect was a "lone individual." But four months after the riot, officials haven't identified the person.

It's still unclear clear if the bombs were planted as part of the insurrection.
