The suspicious person "was assumed" to be W1.
W1 claimed to have been shown by the woman's friends videos on which Williams is purportedly stealing "a laptop computer or hard drive" from the office of the House speaker.
Richard Barnett, a supporter of President Trump, holds a piece of mail as he sits inside the office of Speaker of the House Nancy Pelosi after protesters breached the U.S. Capitol in Washington, D.C., on January 6. He said surveillance video from cameras in the Capitol also show Williams inside the building's Statutory Hall "pointing and directing intruders" during the melee.
The tipster said that the attempt to sell Pelosi's laptop to Russian intelligence fell through for an unknown reason, and either Williams still has it, or it has been destroyed.
The FBI says Williams' mother filed a report with police in Harrisburg about a suspicious person on January 11 but that when officers interviewed her, Williams herself was not present.
Pelosi's deputy chief of staff, Drew Hammill, confirmed January 8 that a laptop was taken from a conference room but said "it was a laptop that was only used for presentations".
How major USA stock indexes fared Thursday
Miners rose 0.8 per cent as fears of tight supply amid fresh virus curbs in China sent iron ore futures higher. Most other major benchmarks rose, with Hong Kong's Hang Seng Index and Japan's Nikkei 225 both up 0.9%.
Williams' ex (identified as W1 in the filing) contacted the Federal Bureau of Investigation and told them she "intended to send the computer device to a friend in Russia, who then planned to sell the device to SVR, Russia's foreign intelligence service", per the court documents.
"At or about 20 minutes and 40 seconds into the video, there appears at the bottom of a staircase the subject, believed to be WILLIAMS, a Caucasian female wearing a green t-shirt and brown trench coat and carrying a black-and-white striped zebra-print bag over her shoulders", the warrant reads. WILLIAMS did not provide her mother any information about her intended destination'.
Williams, who drove from Pennsylvania to D.C. with her father, now appears to be on the run.
Williams' mother, who lives with her in Harrisburg, about 190 kilometres north of the capital, told ITV reporters that her daughter had taken a sudden interest in President Donald Trump's politics and "far-right message boards". The complaint notes that sometime after January 6, Williams also changed her phone number and deleted her social media accounts on Facebook, Instagram, Twitter, Reddit, Telegram, and Parler. Some smashed furniture and scattered documents across the floor while others posed mockingly for photos at her desk.
In another part, one rioter can be heard saying to Capitol Police officers, "You are outnumbered!" The suspicious person "was assumed" to be the same witness who had alleged Williams meant to sell the stolen laptop or hard drive, the bureau says. Charges range from curfew violations to serious federal felonies related to theft and weapons possession.
