Timeline tracks diplomat’s path from college overachiever to alleged highway ‘road rage’ mass stabber

The diplomat accused of fatally stabbing one person and injuring three others in a Sunday highway "road rage incident" once graduated with academic honors and built a career that took him to the U.S. State Department.

Jared Llamado, 32, fatally stabbed Michele Adams, 39, and injured Dana Bonnell, 36, Mary C. Flood, 37, and Heather Miller, 40, according to Virginia State Police. Llamado also stabbed his own dog to death, authorities said. The incident happened on I-495 southbound at 1:17 p.m. in Fairfax County, about 30 minutes from Washington, D.C.

Officials said the stabbings did not appear to be targeted, and none of the victims besides the dog were in Llamado's car at the time. Llamado, who was armed with a knife, was shot by a state trooper in self-defense and died at a local hospital, authorities said. The trooper wasn't injured.

"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," Virginia State Police wrote in a news release. "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."

While working at the Department of State, Llamado said he was living in Copenhagen, Denmark, but appeared to be back in the United States recently.

According to dispatch audio obtained by Fox News Digital, the stabbing 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."
