A 21-year-old Davenport woman was killed late Friday after she was struck by a Union Pacific train in DeWitt, authorities said Saturday.

Clinton County Sheriff Rick Lincoln said deputies were sent at 10:09 p.m. to the rail crossing on 300th Avenue, at the east edge of DeWitt and about a half-mile north of U.S. 30, for a report of a train-pedestrian accident.

Upon their arrival, deputies discovered the body of Kristina Marie Johnson, who had been struck by a westbound train.

Johnson was pronounced dead at the scene by the Clinton County Medical Examiner’s office. An autopsy will be performed at the Iowa State Medical Examiner’s office in Ankeny. The death remains under investigation.

Arrangements for Kristina Johnson are pending at Schultz Funeral Home of DeWitt.

The sheriff’s department was assisted at the scene by DeWitt police, the county medical examiner’s office, Genesis Ambulance-DeWitt, Dewitt firefighters and Union Pacific Railroad personnel.

In September 2003, Johnson’s brother, Cody Moore, 12, and his friend, Brian Gregorich, 13, both of DeWitt, were killed in an accident on the Union Pacific tracks near the Clinton County community.

The boys were walking along the railroad line about three miles east of the city, Lincoln said. They had been standing on the eastbound tracks about a quarter-mile west of the U.S. 30 overpass and were watching a westbound train go by when they were struck by an eastbound train. The passing westbound train apparently distracted the boys, who didn’t see the train that hit them, the sheriff said. At the time, Lincoln said the engineer tried to stop the freight train, which was hauling semi-trailers, but was unable to do so. The train came to rest about 2,000 feet from the point of impact.
