The Ohio State Patrol says 16 people were killed on the state's highways during the five day Thanksgiving holiday period. That number includes 4 fatalities in Southwest Ohio. A head-on crash between two SUV's resulted in the death of 70 year old John Cornelius of Morrow Friday. The wreck happened on Mason Morrow Millgrove Road in Salem Township. There were two fatal crashes in the city of Cincinnati, and one in Clinton County. Of the 16 killed this year, the patrol says two were pedestrians, 10 were not wearing their seat belt, and six of the crashes involved impaired driving. Last year, 17 people died on Ohio roadways. Troopers this weekend arrested 270 motorists for impaired driving, and 130 for drugs. The patrol cited 686 people with safety belt violations and 100 motorists for distracted driving.
