The Indiana State Police is investigating a single-vehicle crash that claimed the life of a Rochester man Monday afternoon.

About 4:30 p.m., troopers responded to calls of a serious vehicle crash on US 31 near 4A Road.  Preliminary investigation indicates that a 2013 Dodge was travelling northbound on US 31 when it ran off the road to the right for an unknown reason, striking a concrete bridge abutment.  Troopers attempted life-saving measures at the scene but the driver, a 35-year-old man from Rochester, was pronounced deceased at the scene.

Neither alcohol nor drugs are suspected to be factors in this crash. 

An autopsy is scheduled for later this week at the Marshall County Forensic Center.
