Two Jackson County residents died as a result of a wreck in southern Bartholomew County that caused a three-hour closure of U.S. 31 Tuesday afternoon, police report.

Kelsey M. LaMaster, 18, of Seymour and Brandon M. Freeman, 24, of Crothersville were pronounced dead by the Bartholomew County Coroner’s Office following a two-vehicle crash reported to police around 2 p.m. near County Road 900S near the Bartholomew/Jackson County Line.

Sgt. Stephen Wheeles, Indiana State Police public information officer, said LaMaster was driving a 1999 Mercury Sable passenger and traveling southbound on U.S. 31 when she lost control of her car for an unknown reason, according to the Indiana State Police-Versailles Crash Reconstruction Team.

The vehicle went off the west side of the roadway, but came back on and crossed the center line.

The vehicle then struck a northbound 2004 Ford F250 pulling a flatbed trailer driven by Paul M. Luedeman, 59, of Crothersville.

Both vehicles then moved off the east side of the roadway and came to a stop. The flatbed trailer disconnected from the truck and continued for another 200 yards off the roadway, according to a news release.

Luedeman sustained serious injuries in the crash and was taken by ambulance to Columbus Regional Hospital in Columbus.

The crash remains under investigation.

Toxicology results on both drivers are pending at this time, police said. U.S. 31 was closed for approximately three hours following the wreck.

The Indiana State Police was assisted by the Bartholomew County Sheriff’s Department, Indiana State Excise Police, Columbus Regional Hospital EMS, Elizabethtown Volunteer Fire Department and Bartholomew County Coroner’s Office.
