A paranormal investigation in Iowa led a Wisconsin man to stab himself on Friday in the same home where two adults and six children were murdered with an ax in 1912, the Daily News reported on Saturday.

Robert Laursen, 37, was investigating the Villisca Ax Murder House, a tourist attraction in a small southwestern Iowa town, for paranormal activity when he stabbed himself in the chest at about 12:45 a.m., according to the Montgomery County Sheriff's Office.

Laursen, a resident of Rhinelander, Wisconsin, was flown by helicopter to Creighton Medical Center in Omaha for treatment after arriving at a local hospital. What he stabbed himself with, his motive, nor his present condition have not been made public.

On June 13 1912, Josiah and Sarah Moore, plus their four children and two other children, were killed by an ax in the house and the crime has been unsolved ever since.

The home has attracted paranormal investigators and tourists since it became listed on the National Register of Historic Places in 1997, the Review Journal reported.
