SARTELL -- A 30-year-old Holdingford woman and her unborn baby were killed in a crash in LeSauk Township Monday morning.  The Stearns County Sheriff's Office says it happened at about 7:45 a.m. at the intersection of County Road 133 and County Road 4, just west of Sartell.

Deputies say a semi driven by 46-year-old Corey Planck of Star City, Indiana was going northeast on County Road 133 toward Sartell.  Meanwhile, the 30-year-old Holdingford woman was going southeast toward St. Cloud on County Road 4.  Her name has not been released yet.

The woman stopped at the stop sign, then proceeded into the intersection.  Deputies say Planck failed to stop at the intersection and struck the woman's car on the passenger side.
