A fun night out at a concert turned deathly for two sisters and friends as their Uber ride is rammed by a speeding car.  The sisters and a life-long friend died while riding in the back seat of a Honda sedan. Another friend and the Uber driver in the front seat were severely injured. The driver who caused the crash, Greg Black, was speeding at up to 100mph, and ran a red light. The Mercedes he was driving hit the other vehicle so hard that it spun around five times, ejecting one of the women.
Black is a known gang member with 11 felony booking and three convictions. He is also on probation for attempted murder.  The 31-year-old faces three counts of vehicular manslaughter.
