UPDATE: Robert Scott Palmer was arrested on March 17, 12 days after HuffPost revealed his identity in this story.

With bright red and white stripes across his body and stars down his sleeves, the man in the American flag jacket and FLORIDA FOR TRUMP hat wielded a fire extinguisher while charging the U.S. Capitol on the afternoon of Jan. 6. He shoved his way through the crowd of rioters to the police line, then sprayed officers at close range before chucking the emptied canister at them. By nightfall he himself had been lightly harmed, apparently by a police crowd control munition. He held up his shirt to show off his bruised gut during an interview with a female journalist filming him live as cops pushed the mob back from Capitol grounds. Then he looked straight into her livestreaming device and identified himself as Robert Palmer from Clearwater, Florida.

At this point, the man had not only assaulted federal officers before a sea of smartphones while wearing highly distinctive attire, hed also willingly revealed his own name and hometown on video at the scene of the crime while still in the same outfit.

This isnt your typical Florida Man story , despite its absurdity. This is the story of a violent insurrectionist whos still at large nearly two months later and one woman who joined the online sleuthing communities crowdsourcing their efforts to bring a Capitol attacker to justice.

Robert Scott Palmer is a white 53-year-old husband and father who runs Son Bright Systems, a cleaning and restoration business. His criminal record includes being sentenced on charges of battery and felony fraud.

HuffPost verified his identity through a search of public records and social media accounts associated with Palmer, after receiving a tip from Amy, a woman living in a rural area out west who in her free time joined the #SeditionHunters network, an online sleuthing community seeking to identify the hundreds of Trump supporters who rioted at the Capitol. (Amy is a pseudonym she chose to protect her privacy.)

Reached by phone late Thursday afternoon, Palmer confirmed he was at the Capitol on Jan. 6 and gave the livestream interview. He claimed that hed done nothing to justify being struck with the police munition, and that the Biden administration was trying to vilify the patriots who were involved in the riot.

Im just going about it and letting them make the mistakes that they want and ruin the country as they want, and Im just trying to live my life right now, he said, adding that the jacket he wore wasnt anything I had made special [I] just bought it in a store.

Palmer seemed to grow increasingly anxious as the call continued.

Im just going to just leave it like that. Im not getting myself any not deeper, cause I didnt do anything wrong but Im not involving myself anymore, he said. He hung up when HuffPost asked him about the fire extinguisher.

While Palmer was storming the Capitol in January, Amy was home sick, thousands of miles away. She had contracted COVID-19 and was getting restless while recovering in isolation. After watching in horror as the insurrection unfolded, she decided to use some of her time in quarantine poring over footage from the attack and trying to track down rioters. Using the Twitter handle @CountryOvParty , she worked with the group @capitolhunters as they tried to mine through a seemingly endless flow of photos and videos, assigning catchy hashtags to various persons of interest to bring some order to the chaos.

The more that I watched [from the insurrection] the more that I felt like I had lost control over what this country was supposed to be, said Amy, who is a federal employee. Spending that time searching was a way to regain control of the situation for me.

The FBI is still hunting down the insurrectionists who flooded the Capitol because they believed former President Donald Trumps false claims about mass voter fraud and supported his efforts to overturn the results of the 2020 presidential election. Its a monumental task. The unprecedented investigation involves hundreds of suspects, hundreds of thousands of tips and millions of pieces of evidence. Keeping it organized and figuring out which suspects the bureau should prioritize is an overwhelming logistical nightmare that few entities even the nations premier law enforcement organization are equipped to handle.

The FBI needs the publics help, and plenty of citizen sleuths are ready to pitch in. But as their investigations move at internet speed, some members of the crowdsourced effort are getting a bit flustered when they send in solid tips, dont hear anything back from the bureau, and have to wonder whether the information they provided got into the right hands.

The FBI does not typically offer comments about ongoing investigations into specific individuals, and the bureau did not do so here.

Amy was among those who wanted to help out. At first, she focused on the man later identified as Robert Sanford , a retired firefighter from outside of Philadelphia who also tossed another fire extinguisher at three cops. He was wearing a CFD hat, so Amy went about researching fire departments in cities that start with the letter C.

I spent hours searching through C-named fire departments throughout the country, primarily in the east or Northeast or Midwest, because where would you need a ski cap? she said. Soon, other online sleuths helped identify Sanford, who had retired last year from the Chester Fire Department in Pennsylvania. He was arrested in mid-January and now faces five federal charges, including civil disorder and assaulting officers using a dangerous weapon.

Amy kept going. She went through every single clip pulled from the right-wing social media website Parler, which were posted and published by ProPublica. She kept going through videos and photos of the attack. Soon #FloridaFlagJacket drew Amys attention. I got locked onto this guy and the jacket, because the jacket is so unique, she recalled.

Palmer wasnt very incognito. His already distinctive jacket was embroidered with TRUMP on the front and back, and his FLORIDA FOR TRUMP hat offered a pretty strong hint about his home state. He was wearing a MASKING UNDER PROTEST mask, a unique item that Amy learned was sold on a Patriots Cave website and can be found on another site called American Patriot Depot.

The pieces were starting to come together. When someone else in the sleuthing community found a video of Palmer later that night, it was the final straw.

Someone else found the YouTube clip where he said his name, and that was the dealbreaker, she said. She sent in another tip to the FBI.

Then she waited. And waited. And waited.
