MADISON, Wis. (AP) -- The patient transported by a medical helicopter that later crashed has been identified as 86-year-old Mary Kricke.

Crawford County Coroner Joe Morovitz says Kricke died hours after getting dropped off at a La Crosse hospital. He says she suffered bleeding in her brain and died early Sunday.

The UW Med Flight helicopter crashed Saturday night on the way home to Madison after transporting her to Gundersen Lutheran hospital from a hospital in Prairie Du Chien.

A doctor, nurse and pilot on board were killed.

National Transportation Safety Board spokesman Keith Holloway says an investigator is studying wreckage recovered from the scene at the airport. He says that process can give clues about what caused the accident.

The NTSB hopes to release a preliminary report on the accident later this month.
