A Corning man who was killed while riding a tricycle has been identified by the Tehama County Coroner’s Office. At around 7:30PM last Wednesday evening, 73-year-old Frank Buchanan was riding a 1990 Summit Trike westbound on South Avenue east of Columbia in Corning. He apparently didn’t see 85-year-old Harry Riggs approaching from behind in his Ford F250. Riggs saw something in the roadway but he thought it was a box. When he got closer he tried to swerve around the object but was unable to avoid hitting what turned out to be Buchanan on the trike. Buchanan was ejected and suffered fatal injuries. The CHP does not believe drugs and alcohol were involved.
