Four people have died in connection to Wednesday's pro-Trump siege on the US Capitol, with one police officer on life support

• Four people have died in connection to Wednesday's siege of the US Capitol.
• One woman was shot, while three others died of "medical emergencies," according to police.
• Kevin Greeson, 55, of Athens, Alabama; Benjamin Phillips, 50, of Ringtown Pennsylvania; and Roseanne Boyland, 34, of Kennesaw, Georgia; all died of "medical emergencies" on Capitol grounds.
• A US Capitol police officer is currently on life support.

The Chief of Metropolitan Police Department of the District of Columbia identified three people who died of "medical emergencies" during the Capitol siege on Wednesday.

Kevin Greeson, 55, of Athens, Alabama; Benjamin Phillips, 50, of Ringtown Pennsylvania; and Roseanne Boyland, 34, of Kennesaw, Georgia; died on Capitol grounds.

Metro police Chief Robert J. Contee III didn't provide details on the exact cause of their deaths, or whether they were taking part in the riots.

"There were a lot of people on the Capitol grounds yesterday and I guess the extent that we can say right now is that they were on the grounds of the Capitol when they experienced their medical emergency," Conte told reporters at a morning press conference. "I can't specify."

Greeson, who died of a heart attack, leaves behind children and a wife in Alabama, his family said in a statement to Insider. He had a history of high blood pressure, according to the family.

His family told Insider he was not inside the Capitol building at the time of his death.

"Kevin was a wonderful father and husband who loved life. He loved to ride motorcycles, he loved his job and his coworkers, and he loved his dogs," the statement said.

"Kevin was an advocate of President Trump and attended the event on January 6, 2020 to show his support. He was excited to be there to experience this event- he was not there to participate in violence or rioting, nor did he condone such actions," it continued. "Our family is devastated. We are thankful for all of the thoughts and prayers and appreciate privacy at this time as we grieve."

In addition to the medical emergency, Air Force veteran Ashli Babbitt was fatally shot while storming the Capitol.

A US Capitol police officer injured in the melee is currently on life support.

Photos and videos of Babbitt inside the Capitol before, during, and after she was shot were shared across social media and after her death, her husband told local media in San Diego - where she was believed to reside - that Babbitt was an ardent Trump supporter.

She posted on social media about her plans to be in DC this week.

"Nothing will stop us," she wrote. "They can try and try and try but the storm is here and it is descending upon DC in less than 24 hours….dark to light!"
