A Lawrence motorcyclist is listed in critical condition at Kansas University Hospital from injuries he sustained in a Saturday afternoon accident near Sixth and Tennessee streets, a hospital spokesman said.

Peter Sander, 33, was driving east on Sixth Street when his motorcycle collided with a car driven by Vera Piersee, 70, Lawrence police said. The woman was attempting to make a left turn south from Sixth Street to Tennessee Street when she crossed the path of the motorcycle, police said.

Sander was flown by helicopter ambulance to KU Hospital in Kansas City, Kan. Witnesses said he was unresponsive at the scene.

Information on whether any citations were issued was not available from police Tuesday.
