LAWRENCE, Kan. (AP) — A Douglas County judge has found a Lawrence man guilty of drug and alcohol-related charges after an accident that caused an 18-year-old University of Kansas student to have both his legs amputated.

After a bench trial last week, 24-year-old Julian M. Kuszmaul was found guilty of second-offense DUI, refusing to submit to alcohol or drug testing and possession of marijuana.

Kuszmaul struck 18-year-old Colby Liston, who is now 20, in August 2012 on a Lawrence street. Liston was pinned between Kuszmaul’s vehicle and another car. He later had to have his legs amputated.

6NewsLawrence reports (http://bit.ly/1DRkdyi ) Kuszmaul’s blood-alcohol level was 0.25 at the time of the accident.

Each of Kuszmaul’s convictions is a misdemeanor. Sentencing is scheduled for Jan. 22.
