Woman sues husband who is accused of shooting her

A woman whose husband is accused of shooting her multiple times at their Town of Grafton home in October 2025 filed a civil lawsuit against him Monday that contends he wanted a divorce and told her repeatedly he would obtain full custody of their children and keep all of the couple’s  assets.

Shirley Aliaga Paider is seeking unspecified compensatory and punitive damages from Guy J. Paider as well as an injunction that would prevent him “wasting his assets or fraudulently transferring any asset before or after entry of judgment in this matter,” according to the lawsuit.

Ultimately, it was Aliaga Paider who filed for divorce, and hours later on Oct. 24 Paider shot her in their bedroom as officers called by their daughter searched the house for her, according to a criminal complaint filed in Ozaukee County Circuit Court charging Paider with attempted first-degree intentional homicide and first-degree reckless injury.

Paider is being held in the county jail in lieu of $3 million bail. The lawyer representing him in the criminal case, Benjamin Lutgen, did not respond to messages seeking comment.

Paider has pleaded not guilty to the charges.

According to the lawsuit, Paider began telling his wife in June 2025 that he wanted a divorce and would obtain full custody of their children, she would be forced to leave their house and he would retain all their assets because he worked full time and she had only worked part time.

Aliaga Paider told Paider she would not consent to him having full custody of the children, would not leave the house and that their assets were joint marital property.

Paider did not give his wife access to any of their financial accounts and allowed her to use her debit or credit card only to purchase food or gas, according to the lawsuit.

The terms of the couple’s divorce continued to be a source of contention, the lawsuit states, and on Oct. 4 Paider drove his wife to the Immigration and Customs Enforcement office in Green Bay, telling her he would ensure she was deported even though she is a citizen of the United States. The deportation attempt was unsuccessful.

On Oct. 10, the lawsuit contends, Paider drove his wife and their children to their second home in Manitowoc County, left the children there and drove his wife back to their Town of Grafton house, where he told her to pack her belongings and leave the house by the time he and their children returned three days later. She refused.

On Oct. 24 — the day of the shooting — Aliaga Paider met with her attorney to finalize her divorce filing and returned home. At 3:50 p.m., authorities were called to the couple’s house off Highway C by their daughter, who reported a fight between her parents.

  Officer Patrick Brock and Sgt. Noah Eernisse of the Grafton Police Department were the first to arrive at the house and were let in by the girl, who reported that her mother told her to call 911 and her father told her to get out of the house, according to the criminal complaint

The officers noticed signs of a struggle in the kitchen, and after announcing their presence they heard a woman screaming in a back bedroom, Ozaukee County Sheriff’s Office detective Zachary Gierach testified during a Dec. 1 preliminary hearing.

The door to that room was locked, so Brock kicked it in and told the people inside to come out with their hands up. That is when Brock heard multiple gunshots. His body camera recorded the sound of four shots, the complaint states.

Believing the shots were being fired at them, Brock and Eernisse retreated down the hallway and again ordered the people in the bedroom to show their hands. Paider announced he was coming out of the room with his hands raised, then surrendered to the officers, according to the complaint.

Eernisse went into the bedroom to find Paider’s wife on the bed shot multiple times, including in the abdomen, leg and groin, and rendered aid until emergency medics arrived. She was taken by ambulance to Aurora Medical Center in Grafton, then flown by a Flight for Life helicopter to Froedtert Hospital in Wauwatosa.

In the bedroom officers found a Kimber 1911 semi-automatic handgun with a bullet in the chamber and two in the seven-round magazine. Four bullets and shell casings were recovered from the room.

Three days after the shooting, Aliaga Paider told Gierach and another detective, who interviewed her in her hospital room, that after meeting with her lawyer regarding her divorce on Oct. 24, she went home to find Paider and their daughter cooking in the kitchen. She said her husband repeatedly asked her what she wanted in the divorce and she said she didn’t want to talk about it in front of their daughter, according to the complaint.

She said Paider sent their daughter to her bedroom, then threw her to the floor. She said she hit her head and began yelling for her daughter to call 911, the complaint states.

Paider then covered her mouth, Aliaga Paider said, picked her up and carried her to the bedroom, where he threw her to the floor again. She said she covered her face with her hands and began screaming “no, no,” then opened her eyes to see Paider retrieving his gun from the underwear drawer of his dresser, according to the complaint.

She said Paider told her, “Look at me. Look at me so you can see me when I shoot you” as she pleaded with him not to shoot, the complaint states.

“She said she refused to look at him,” Gierach testified.

In her lawsuit, Aliaga Paider said her husband pointed the gun at her and asked, “Is this what you wanted? You want our children to have no parents?”

She said she was covering her face with a pillow when Paider again demanded she look at him and said, “You called the sheriff. They are here. That’s what you wanted.” Then, she said, Paider shot her, the complaint states.

According to her lawsuit, Aliaga Paider underwent multiple surgeries and was hospitalized for weeks.

Paider is a former longtime member of the West Allis Fire Department. According to the department’s 2022 annual report, he worked for the department for more than 26 years and served as its battalion chief. He also worked as a nurse with emergency room experience and served as an EMT-paramedic instructor at Milwaukee Area Technical College.

In addition, Paider served as the town representative on the Grafton Public Safety Committee for a short time.
