WICHITA, Kan. (AP) — A Wichita police officer who crashed his vehicle while speeding without lights or sirens has been fired.

The Wichita Eagle reports Officer Samuel Dugo is charged with aggravated battery-recklessly causing bodily harm after the March 2018 wreck critically injured a 71-year-old. He has pleaded not guilty.

Police spokesman Officer Kevin Wheeler said Dugo’s employment ended Aug. 30. He was with the department since July 2016.

The Kansas Highway Patrol says Donald Clark, of Bel Aire, was thrown through the windshield of his truck when it collided with Dugo’s vehicle at a Wichita intersection.

The patrol determined Dugo was driving 79 mph in a 30 mph zone before the collision, while responding to a burglary call. He was not using his emergency lights or sirens. Before the collision, Dugo was clocked at 100 mph.
