According to White House Correspondent Wid Lyman, "Four stabbing victims were located at scene. One, a 39-year-old female, has since succumbed to her injuries. A dog was also stabbed and is deceased. A Virginia State Police trooper was called to the scene at approximately 1:17 p.m. for a reported road rage incident. When the trooper arrived on scene, he was confronted by a male suspect carrying a knife. The trooper then shot the suspect in self-defense."

An unverified report from an alleged eyewitness of the incident posted to the Northern Virginia Reddit page that the suspect "drove up from behind and smashed car in left lane, approx 70mph, car crosses 4 lanes to pull over on shoulder, guy continues following him and smashing into him.

"We drove past at this point but presumably next steps were them getting out and guy initiating the stabbing. It was truly insane and terrifying even when we didn’t yet know about the stabbing."

Virginia State Police have not released details about what led to the roadway shutdown, according to WUSA. A spokesperson told the outlet he could not confirm information about “the incident on the Beltway.”

Video from the scene posted to social media show an air ambulance arriving on the scene.
