A woman and her dog were killed and three other women were seriously injured after an apparent road rage crash on the Capital Beltway escalated into a stabbing attack and an officer-involved shooting Sunday afternoon.
The incident unfolded shortly after 1 p.m. March 1 on southbound Interstate 495 near Exit 52 in Fairfax County, where a crash led to a confrontation on the roadway, according to Virginia State Police. Officials said the incident is not believed to be related to terrorism.
When a Virginia State Police trooper responded around 1:17 p.m. to reports of a road rage incident, he encountered a man armed with a knife, according to the agency.
State police said four stabbing victims were found at the scene, including Michelle Adams, 39, who died from her injuries, and a dog that also died from stab wounds. The three surviving victims—women ages 36, 37, and 40—were taken to local hospitals with serious injuries.
The trooper involved has been placed on administrative leave pending the outcome of the shooting investigation, which is being handled by the Virginia State Police Bureau of Criminal Investigation’s Fairfax Field Office.
While investigators say there is no indication the prior incidents are connected or all fueled by road rage, the agency is using the moment to renew warnings about aggressive driving and confrontations on crowded roadways.
The AAA Foundation study found that exposure to aggressive behavior behind the wheel often leads drivers to act more aggressively themselves, creating what the group described as a self-perpetuating cycle of hostility on the road.
“Public safety is our top priority and concern. We ask all motorists to drive defensively in order to protect yourself and others on the roadways,” Colonel Matthew D. Hanley, superintendent of the Virginia State Police, said in a statement.
Between Jan. 1, 2023, and Oct. 13, 2025, there were 236 reported shootings on Virginia highways, with 99 in 2023, 86 in 2024, and 51 at the time in 2025.
“Our study finds that experiencing various forms of aggressive driving behaviors is common for almost all motorists and many drive aggressively,” said Dr. David Yang, president and executive director of the AAA Foundation for Traffic Safety.
