What we know about the "unprecedented" U.S. Capitol riot arrests
CBSN
America watched as hordes of rioters broke into the U.S. Capitol on January 6 — crushing through windows, pressing up stairways, and sending lawmakers and law enforcement running for their lives. The flood of protesters who streamed into the Capitol that day left federal authorities with an equally immense task: finding and charging those responsible.
The Department of Justice told CBS News that as of May 6, approximately 440 defendants had been arrested since the attack. The government has said in court filings that in addition to the more than 400 people who had already been charged, federal prosecutors still expect to charge at least 100 more. Prosecutors have called the case "unprecedented" in scale, and the government said in a March court filing that the Capitol attack "is likely the most complex investigation ever prosecuted by the Department of Justice."On Nov. 13, 2016, Dr. Eric "Scott" Sills, a renowned California fertility doctor, called 911 and reported finding his wife and business partner Susann Sills unresponsive at the bottom of the stairs. An initial investigation revealed some evidence that was consistent with an accidental fall. But as "48 Hours" correspondent Tracy Smith reports, other evidence pointed to something more sinister. DETECTIVE: How do you know she — she got an email? MARY-KATHERINE SILLS: I woke up and my dad was just like on the covers just laying there like there wasn't enough room to get in I guess. So, he was just laying there.
