OSHKOSH, WI (WTAQ-WLUK) – A deadly Oshkosh shooting was prompted by a disagreement about repairs to a vehicle and relationship issues, according to a criminal complaint filed Monday.
On Aug. 4, Joshua Aide allegedly shot his ex-girlfriend Rebecca Borkowski, 33, shot and killed her father, James Gruettner 59, and shot another man, John Miller, 57, who was at the Minnesota Ave. home to repair a radiator.
Aide was arrested in Green County a few hours after the shooting.
He is charged with one count of first-degree intentional homicide, and two counts of attempted homicide.
Aide and Borkowski co-owned a vehicle.
“The Defendant became upset over the fact that someone was going to be working on his vehicle,” the complaint states.
After his arrest, Aide denied killing anyone. But shortly after the shooting, admitted to a friend about his role in the shooting, according to the complaint.
Aide and Borkowski dated about five years before breaking up in March. In the days before the shooting, the two exchanged messages in which she declines his requests to get back together, the complaint states.
“The messages between the Defendant and (Borkowski) from the day of the shooting address the work (Borkowski) was planning to do on their mutually-owned vehicle. (Borkowski) indicates that she is replacing the radiator and someone is coming to help her. The Defendant demands that she stop whatever she is doing. He suggests that he drive up and help her. (Borkowski) declines his offer and states she wants the vehicle “outta here this weekend.” The Defendant continues sending her messages stating “don’t touch the radiator.”
Aide made an initial court appearance Monday, where a $6 million cash bond was set.
He returns to court Aug. 17 for further proceedings, with a preliminary hearing set for Aug. 20.
