[Government?] [i]nvestigators hired a biomechanical engineering firm to recreate Jewel Schirmer’s supposed fall down the stairs. The firm used a test dummy fitted with various instruments to collect data on the forces to which her tumbling body would have been subjected.
"We found the ’crash dummy’ evidence to be particularly compelling, as it indicated to us that Jewel could not have suffered all of her injuries by accidentally falling down a flight of stairs," the grand jury wrote.
The grand jury cited medical testimony that revealed Schirmer likely used blunt objects to kill both his wives.
"We find it particularly disturbing and difficult to believe that both of A.B. Schirmer’s wives could have suffered such horrific injuries by accident. To the contrary, we believe probable cause exists to believe that neither woman died from an accident," the report said.
