Oskaloosa - A July 14 preliminary hearing was set this morning for a Kansas City, Kan., man who is charged in a March traffic accident in which the son of former Jefferson County Sheriff Rex Johnson was killed.
Robert G. Cernech, 38, is charged with involuntary manslaughter, driving under the influence of alcohol or drugs, transporting an open container of alcohol, driving left of center and failing to use his seat belt.
The manslaughter charge alleges Cernech killed David B. Johnson, 31, Lawrence, unintentionally while driving under the influence of alcohol.
The Kansas Highway Patrol report indicates Cernech's blood alcohol content was 0.23 percent, nearly three times over the legal limit for intoxication in Kansas of .08 percent.
The accident occurred shortly before 8 a.m. March 29 on U.S. Highway 24 about 3 miles east of the U.S. Highway 59 junction.
The report indicates that Cernech's eastbound minivan went left of center and struck Johnson's westbound tractor-trailer truck nearly head-on. A front-end loader that Johnson was hauling on a flatbed trailer behind the truck rolled forward, broke the chains that were securing it to the trailer and rolled onto the cab of the truck.
