A Port Byron man pleaded not guilty in Cayuga County Court Tuesday to 10 charges stemming from a March incident in which he is accused of attempting to hit a Wayne County Sheriff's Deputy with a van.

Dale Rigby, 39, of 3 Bells Way, Port Byron, is charged with four felony crimes: first-degree attempted assault of a police officer, first-degree attempted assault with intent to cause serious injury, reckless endangerment and unlawful imprisonment. He is also charged with six misdemeanors.

In June, Rigby rejected a plea offer that would have required him to serve a minimum of 3.5 years in prison. During that court session, Rigby said he would plead to a lesser charge of reckless conduct, but not to intentionally trying to hit the deputy.

Rigby is accused of leading Wayne County Sheriff's Deputy George Lorenz on a March 17 high-speed chase that started in that Wayne County and ended on East Lake Road, in Conquest.

When Rigby ended up on a dead-end road, police said, he turned around and drove directly at Lorenz, who had exited his patrol car.

Lorenz fired nine rounds at the vehicle's tires, causing Rigby to lose control of the van and crash into a snowbank.
