One man is dead following a motorcycle crash early Wednesday morning at 9th and Hickman.

Des Moines Police Sgt. Jason Halifax says, "Initial appearances are that the SUV turned in front of the motorcycle, and that the motorcycle collided with the rear passenger door of the SUV."

Halifax says the driver of the motorcycle was not wearing a helmet, and was pronounced dead at the scene. His name is being withheld pending notification of family.

The female driver of the SUV was taken to the Des Moines Traffic Unit for questioning, however speed and impaired driving appear not to be factors in the investigation.
