A Holdingford woman and her unborn baby were killed after a semi slammed into their S-U-V Monday morning near Sartell. The Stearns County Sheriff’s Office says a semi driven by an Indiana man failed to obey a stop sign at a four-way intersection and struck the woman’s vehicle on the passenger side. Deputies say 30-year-old Casey Rose Myers was unconscious and not breathing when she was taken to St. Cloud Hospital and she and her five-month-old fetus did not survive. The truck driver told investigators he didn’t see the stop sign.
