Minnesota woman found dead in wreckage of small plane in Northeast Mo.

KNOX CITY, Mo. (AP) -- A homemade airplane crashed in a northeast Missouri field Monday, killing one person and injuring two others, the Missouri State Highway Patrol said.

A trooper found the wreckage shortly after 3:30 p.m. after spotting smoke coming from the field, the patrol said. The plane had been en route from Florida to Spicer, Minn., according to the patrol's preliminary investigation.

Kimberly Woltjer, of Pennock, Minn., was pronounced dead at the scene, the patrol said.

Her husband, Richard Woltjer, and the pilot, Gene Underland, of Spicer, Minn., were found near the crash site, both with serious burns, the patrol said. The two men were flown to Blessing Hospital in Quincy, Ill., and were later transferred to the St. John's Hospital Burn Center in Springfield, Ill.

The cause of the crash was undetermined Monday. Investigators from the Federal Aviation Administration and the National Transportation Safety Board were expected to go to the site Tuesday.
