CAPE CORAL, Fla.- Yesterday evening around 6:00 p.m., Cape Coral Police responded to a serious traffic crash in the 2300 block of Del Prado Boulevard S., near Veterans Memorial Parkway.

The crash involved a car and a motorcycle, and as a result of the crash, the motorcyclist was ejected and sustained, what was believed to be at the time, life-threatening injuries. The motorcyclist’s condition has since been downgraded to serious, but non-life-threatening.

The investigation has revealed that alcohol and/or drugs are a factor.

The motorcyclist has been identified as 60-year-old Leonard Mark Chaifetz. Chaifetz was transported to Lee Memorial Hospital as a trauma alert.

Kathleen Ann Francois, 48, the driver of the other vehicle, was not injured in the crash.

For unknown reasons, Chaifetz changed lanes from the middle lane into the inside lane, causing him to hit Francois' vehicle.

Chaifetz was not wearing a helmet at the time of the traffic crash.
