Federal prosecutors say the former commander of the Ohio Highway Patrol's Marietta post accused of stalking a subordinate's wife put a GPS tracking device on her car so he could follow her. A newly filed criminal complaint accuses William Elschlager of cyberstalking and deprivation of rights under color of law. An FBI affidavit says the 48-year-old Elschlager had an affair with a colleague's wife in 2015 and began stalking her after the relationship ended. State charges related to stalking and accessing personal information about 10 other women from a law-enforcement database have been dismissed.
