SCOTTSDALE, AZ (3TV/CBS 5) -- A second man has been arrested on second-degree murder charges in a deadly Scottsdale racing crash earlier this month.
The accident happened on the afternoon of Aug. 3 at the intersection of Williams Drive and Miller Road, and left a 68-year-old woman dead.
Police believe the two suspects were racing before the collision.
One suspect, 22-year-old Ramon Angel Carrasco, was arrested shortly after police say his BMW collided with the victim's car.
And now, police have arrested another man who was allegedly racing with Cassrasco prior to the collision.
Police say 59-year-old Robert J. Foster, of Scottsdale, was driving a Lamborghini in excess of 100 MPH just before the crash.
The victim, later identified as Cynthia Ann Fisher, was driving by herself southbound on Miller Road, about to make a left turn on Williams Drive, when one of the racing vehicles crashed into her car.
Fisher was critically injured in the crash and later died at the hospital.
Carrasco and his female passenger had minor injuries and received treatment at a local hospital. He was arrested a short time later on charges of second-degree murder and aggravated assault.
But it wasn't until this week that police arrested the other alleged racer, Foster.
Foster is being held in custody on charges of second-degree murder and aggravated assault.
