Washington: The US Capitol Police said Ashli Babbitt, was shot by an employee of Capitol Police while rioters were moving toward the House chamber on Wednesday.
She died at a hospital.
The San Diego woman who was fatally shot by police inside the U.S. Capitol had a history of social media rants against many of President Donald Trump's favorite targets - illegal immigration, masks and his critics.
Babbitt frequently posted unsubstantiated comments online about election fraud by the president and his most extreme supporters.
Police say the 35-year-old joined thousands of rioters who stormed the U.S. Capitol.
Her husband says that "she loved her country, and she was doing what she thought was right to support her country."
District of Columbia police have identified the three other people who had medical emergencies and died during the storming of the Capitol.
They are 55-year-old Kevin Greeson, of Athens, Alabama; 34-year-old Rosanne Boyland, of Kennesaw, Georgia; and 50-year-old Benjamin Philips, of Ringtown, Pennsylvania.
Police Chief Robert Contee would not go into detail about the exact cause of their deaths and would not say if any of the three was actively involved in breaching the Capitol building on Wednesday.
Contee would only say that all three "were on the grounds of the Capitol when they experienced their medical emergencies."
Greeson's family says he had a heart attack. They described him as a supporter of President Donald Trump's but denied that he condoned violence.
The siege at the Capitol by Trump loyalists came as Congress was certifying President-elect Joe Biden's victory.
