The suspect in a highway "road rage incident" Sunday that left one woman dead and the alleged attacker fatally shot by police has been identified by authorities as dispatch audio reveals how it all started.

In a news release, the Virginia State Police said that 32-year-old Jared Llamado of McLean allegedly stabbed Michelle Adams, 39; Dana Bonnell, 36; Mary C. Flood, 37 and Heather Miller, 40. Adams died as a result of her injuries. A dog was also killed in the stabbing attack. The incident happened on I-495 southbound at 1:20 p.m. in Fairfax County, about 30 minutes from Washington, D.C.

Officials said that the stabbing followed a crash and isn't believed to be terrorism-related. 

The Virginia State Police said Llamado confronted a trooper that arrived on scene, who then shot the suspect who was armed with a knife. Llamado died at a local hospital as a result of his injuries.

The state trooper wasn't injured in the shooting.

"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 Virginia State Police wrote. "The trooper then shot the suspect in self-defense. The suspect, Jared Llamado, 32, of McLean, Va., was transported to the hospital with serious injuries. Llamado later succumbed to those injuries. The trooper was not injured."

Dispatch audio reviewed by Fox News Digital states that the incident "started out as a property damage crash," then the suspect began "stabbing people with a knife."

The dispatch operator said that there were "multiple victims in the roadway."

Officials shut down a portion of the highway while police responded.

"I-495 and 495 Express Lanes southbound past Gallows Road is closed due to a major incident," the Virginia Department of Transportation’s Northern Virginia office said.
