On Monday, October 14th at approximately 3:30 p.m. Dakota County Sheriff’s Office deputies
responded to a two-vehicle head on crash on County Road 46 (160th Street West) near Biscayne
Avenue in the City of Rosemount.
Witnesses reported a 2012 Ford Fusion, driven by David Rosas (15) of Rosemount, traveling east
on County Road 46 near Biscayne Avenue. Rosas was behind a semi-truck and pulled into the
westbound lane in a no passing zone in an attempt to pass. Witnesses reported an oncoming
westbound vehicle approaching approximately one-quarter of a mile away, a 2014 Lincoln MKX,
driven by Dennis Dahlstrom (81) with passenger Sandra Dahlstrom (78) of Champaign, Illinois.
Each driver swerved onto the north shoulder at the same time and collided.
The drivers, David Rosas and Dennis Dahlstrom, sustained fatal injuries and were pronounced
deceased on scene. The passenger of the Lincoln, Sandra Dahlstrom, sustained critical injuries and
was transported to the hospital.
In this tragedy, there were several heroic citizens that stopped to render aid to the victims before
first responders arrived. We also thank those responding agencies who assisted in life saving
efforts; Rosemount Police Department, Rosemount Fire Department, Allina Health, and the
Minnesota State Patrol.
We extend our deepest condolences to the victims’ families and friends involved in this tragic
incident.
