A Lecompton man has been bound over for trial for causing a fatal crash near Wamego last summer.

An all-day preliminary hearing was held Thursday in Pottawatomie County District Court for 45-year-old Mark Stanwix.

Judge Erich Campbell found there was sufficient evidence to bind Stanwix over on two counts of involuntary manslaughter, three counts of aggravated battery and a single count of interference with law enforcement, for destruction of evidence.

Arraignment is tentatively scheduled for July 21, with a trial date to be determined.

Stanwix was driving a semi truck that rear-ended a pickup last August, east of Wamego. The crash claimed the life of a 37-year-old Wamego man and his 7-year-old son, and seriously injured the man’s wife and 2-year-old son. A St. Marys woman was also injured in the crash.

A civil suit filed last fall by the two surviving women, alleges Stanwix was using his phone at the time of the crash.
