Police say speed was a factor in the South Cooper Street collision and are working to determine whether the Mercedes driver was racing before the crash.

The TPD said Video evidence indicated the BMW was racing another vehicle at the time of the crash.
Witnesses told police that the driver of a high-performance BMW was street racing.
