Police have released the identities of those involved in a fatal single-vehicle crash over the weekend in Davie.
Police said Zachary March Libman, 28, was driving his 2013 BMW M5 Saturday night at a high rate of speed in the area of 11100 Griffin Road when he lost control of his car.
Police said the car slid sideways, entered a ditch and rolled over several times.
One of the passengers was ejected from the car and struck a tree, authorities said. That person, identified as Scott Frederick Garnto, 28, was pronounced dead at the scene.
Police said Libman and another passenger, Paris Jason Henderson, 28, were taken to a local hospital in critical condition.
A witness took a short video of a motorcycle that they told police was also driving erratically on Griffin Road just before the crash.
The video shows the motorcyclist spinning his tires at the intersection of Flamingo Road and Griffin Road before the light turned green.
The BMW is seen in the distance turning east onto Griffin Road as the motorcycle proceeds through the intersection.
Police believe the motorcyclist might have witnessed the crash.
"We believe that the motorcycle was not directly involved in the crash," Davie police spokesman Mark Leone said. "We believe that the BMW lost control, left the roadway. We do believe that he (the motorcyclist) may have seen something."
Anyone with information about the motorcyclist's identity is asked to call Davie police at 954-693-8200 or Broward Crime Stoppers at 954-493-TIPS.
