"We're unsure yet who started this fight, how the swordplay got involved," Mount said. "We're not sure who it was who stabbed the woman. We'll have to do some testing on the swords and figure out who had which sword, whose blood is on which sword."
One of the weapons was a World War II-era Japanese officer's sword with a thin blade, and the other had a thicker blade, Mount said.
Police placed Stegbauer's grandson, 39-year-old Chris Rondeau, under arrest on a preliminary charge of attempted murder. Stegbauer's brother-in-law, 69-year-old Adolf Stegbauer, suffered several serious stab wounds, police said.
Franziska Stegbauer was not breathing when officers arrived about 1 a.m. at the home on the city's northwest side and she was later pronounced dead at a hospital, police said.
Ok parents. Lock up all your weapons. Your guns and your swords.
