A preliminary federal report suggests that icy conditions will be among the factors checked by investigators trying to determine what caused the fatal crash of a medical helicopter in northern Iowa.
Mason City television station KIMT says the report released Wednesday did not include any conclusion about the crash cause. The pilot and two others on board died the night of January 2.
The helicopter had been headed to Emmetsburg, about 80 miles west of Mason City, to pick up a patient when it slammed into the ground just north of Ventura about 9 pm. The report says several witnesses mentioned icy conditions at the time.
The three victims were identified as nurse Shelly Lair-Langenbau, paramedic Russell Piehl and pilot Gene Grell.
