The driver of the blue Ford Mustang involved in a fatal crash in Kingstowne last month admitted to speeding before the collision, according to police documents.

A witness also reported to police that the Mustang's driver accelerated immediately before the crash.

The crash, at the intersection of Kingstowne Boulevard and Kingstowne Village Parkway, occurred around 1:15 p.m. on January 29, when the Mustang traveling east on Kingstowne Boulevard struck a silver Toyota Camry that was turning left from the boulevard onto Kingstowne Village Parkway. Both cars were facing a yellow light, according to a search warrant request for the Mustang's air bag data.

The Mustang struck the Camry's passenger side, killing Diana Merediz, a 71-year-old Mount Vernon woman. The Camry's driver was taken by helicopter to Inova Fairfax with life-threatening injuries, while the Mustang's driver received non-life-threatening injuries.

Following the crash, the Mustang's driver, a Franconia man, allegedly admitted to police that he accelerated because of the yellow light, according to the search warrant, and was traveling above the speed limit. This account was confirmed by a witness to the crash, according to the document.

The search warrant, filed by Fairfax County Police Department Detective Joshua David, seeks to obtain information about the Mustang's velocity and acceleration before the crash.
