(Lake View, Iowa) – A single-vehicle accident Sunday night in northwest Iowa’s Sac County resulted in a fatality and one person with injuries. The Iowa State Patrol reports a 2014 VW Passat driven by 22-year-old Oliver Massman, of Holman, WI, was southbound on Perkins Avenue near 350th Street, when for reasons unknown, the vehicle entered the west ditch and traveled up an embankment, before it struck and broke a utility pole.

The car continued, vaulted and struck a tree, overturned and entered a pond, with the front end being submerged in the water. The accident that occurred south of Lake View, happened at around 6:55-p.m. Authorities say life saving measures were attempted on Massman, but were unsuccessful. A passenger in the vehicle, 22-year-old Ean Marker, of Waupaca, WI, was injured and transported by Sac County Ambulance to Loring Hospital in Sac City, and later flown by Lifeflight to Mercy Hospital in Sioux City.  Neither man was wearing a seat belt.

The accident remains under investigation, but the Patrol said speed and alcohol are suspected factors in the crash.
