A car rammed a barricade at the U.S. Capitol, killing one police officer and injuring another. The officer who lost his life is named William Evans. The suspect was identified as 25-year-old Noah Green from Indiana, and has been confirmed as dead. The Capitol was placed on lockdown, with people told to shelter in place and avoid doors and windows. The incident occurred at a checkpoint near the northern entrance, and Greene was said to have exited the vehicle with a knife after crashing the car.
