Joshua Aide, 40, stands trial in Winnebago County, Wisconsin after prosecutors said he tried to kill his ex-girlfriend Rebecca Borkowski, 33, and another man John Miller, 57, and also murdered his ex’s father James Gruettner, 59. You can watch in the player above.
Borkowski dumped Aide after five years together, and rejected his attempts to get back together, citing physical abuse including choking. Prosecutors said the August 4 shooting happened amid a dispute over a vehicle they both owned. Borkowski wanted to replace the radiator, and she refused his help. She said she wanted the vehicle gone by the weekend. Someone was coming to help her fix it. Aide, however, allegedly insisted that no one touch the radiator.
The defendant allegedly opened fire on the three victims as they were working on the vehicle. Borkowski survived a gunshot wound to the ear and the back of her head. Miller survived a shot to the face. Gruettner, however, died from a shot to the forehead.
Aide is charged with first-degree intentional homicide, and two counts of attempted first-degree intentional homicide. He recently walked back an insanity defense. Filings back in January showed that he was getting ready to argue self-defense at trial.
