Detectives Investigate Fatal Single-Vehicle Crash in Oakton

Posted on by

Fair Oaks Police District – Detectives from our Crash Reconstruction Unit (CRU) are investigating a fatal single-vehicle crash in Oakton that left two people dead and two children injured.

On May 17, at 12:28 a.m., officers responded to Chain Bridge Road over I-66 for a single-vehicle crash involving a 2020 Mercedes GLA 250.

Preliminarily, detectives determined the driver of the Mercedes, Xiomara Herrera, 30, of Falls Church, was traveling eastbound on the I-66 Express Lanes when she took the exit ramp to Chain Bridge Road. The vehicle continued through the intersection, crossed over the raised median, and struck a concrete barrier.

Herrera was pronounced deceased at the scene. The front passenger, Alejandro Rodriguez Castillo, 27, of Sterling, was transported to a local hospital where he was later pronounced deceased.

A two-year-old child was transported to a local hospital with life-threatening injuries and remains hospitalized. An eight-year-old child was transported to a local hospital with non-life-threatening injuries.

Preliminarily, detectives believe speed was a factor in the crash and that the eight-year-old was the only occupant who was properly restrained.

Victim specialists from our Major Crimes Bureau’s Victim Services Division have been assigned to ensure the family is receiving appropriate resources and assistance.
