A Wisconsin woman has been taken into custody after allegedly killing her mother with a four-pound rock, according to local authorities.

Lauren Spors, 29, faces charges of first-degree intentional homicide and domestic abuse, as confirmed by the Milwaukee County Sheriff’s Office.

The tragic incident unfolded on October 12, just after 2 p.m., when 64-year-old Carrie Zettel dialed 911, reporting her daughter’s violent behavior, according to law enforcement officials.

By 2:20 p.m., officers arrived at the home on West Ramsey Avenue, where they discovered Zettel with severe head trauma, her injuries so grave that brain matter was visible, as detailed in a search warrant obtained by Milwaukee’s CBS affiliate WDJT.

Authorities pronounced her dead at the scene shortly after their arrival. A large, blood-stained rock was found on the grass near Zettel’s body. Police noted that Spors was also covered in blood, presumably from the attack on her mother.

Additional evidence was gathered to support Spors’ arrest, according to police reports.

Another 911 caller reported seeing the younger woman standing over the older woman in the backyard, holding a large object, and repeatedly bringing it down upon the victim, according to a criminal complaint obtained by Milwaukee-based Fox affiliate WITI.

Some believe the alleged matricidal violence was a long time coming.

Loretta Moyer, a close friend of the victim, told WDJT that Zettel believed her daughter killed her own father back in January 2018.

In fact, Zettel told police her daughter “hit” Jeffrey Spors “over the head with two glass bottles,” according to a report issued by the Milwaukee County Medical Examiner’s Office. Law enforcement, however, learned the dead man “was known to over medicate on his pain prescriptions” and declined to charge his daughter with a crime.

Still, Lauren Spors would be served with a domestic violence restraining order prohibiting her from contacting her mother in the months following her father’s death, WDJT reported. And, she would allegedly go on to twice violate that order – which was in effect until 2022. Each time, the woman was deemed mentally incompetent to stand trial.

“I haven’t accepted my dad’s death,” the alleged murderess once wrote to a judge in 2018 after the initial protective order violation. “My mom says I killed him, but I don’t remember doing it.”

Lauren Spors accepted some level of culpability for her violation, though, acknowledging her mental illness caused her to act out.

Over the past seven years, with her daughter in and out of relatively minor legal trouble, as well as institutions and hospitals, Zettel began to fear for her life, Moyer told the CBS affiliate.

Roughly two weeks before her death, the soon-to-be-killed woman made a chillingly prescient statement, the family friend said.

“Carrie even said, she goes, ‘Maybe if she kills me, she’ll get the help she needs,’” Moyer said, “Carrie was hopeless at this point.”

During the early morning hours on the day of the death, Zettel called Moyer and left a voicemail about her daughter, WDJT reported.

“Lauren was here just now, pounding on the doors, the windows. I called 911,” Zettel can be heard saying. “The police came, and they caught her under a tarp and she ran away, so I don’t know. They’re still here. They’re gonna try to look for her.”

That effort apparently did not pan out.

Lauren Spors is detained in the Milwaukee County Jail on $100,000 bond. The defendant is next slated to appear in court on Nov. 21.
