Angelynn Mock walked out of a Wichita courtroom in tears on Friday, August 21. Minutes earlier, the 48-year-old had pleaded guilty to first-degree murder, the stabbing death of her own 80-year-old mother inside the home they shared.
Seven months earlier, a judge had ruled she wasn’t well enough to stand trial at all.
Nothing about the crime changed in those seven months. The facts of that October morning were the same in August as they were in January. What changed was a legal finding about the woman herself, and that reversal is the part of this case people can’t stop arguing about.
The woman who called 911 had made the call necessary
Just before 8 a.m. on October 31, 2025, on Halloween morning, a woman covered in blood approached a car parked near a home on Wichita’s south side and asked to borrow a phone. She needed to call 911, she said. Then, according to a neighbor who spoke to Wichita ABC affiliate KAKE, she took the phone and went back inside to make the report herself.
The caller was Angelynn Mock. Dispatchers relayed her account to responding officers in a single chilling line: she had stabbed her mother “to save herself.”
Police arrived to find Mock outside with cuts on her hands. Inside, 80-year-old Anita Avers lay unresponsive in her bed, stabbed multiple times. She died at the hospital a short time later.
A therapist and an anchor, in the same house
For years, Anita Avers worked in Wichita as a marriage and family therapist, the person other families came to when something broke.

Her daughter had a public life of a different kind. Mock anchored the morning news at FOX 2 in St. Louis from 2011 to 2015, with earlier television stops in Oklahoma City, before moving into data and sales work. Two women who’d built their lives on being trusted, in the same house on the same Halloween morning, and only one of them walked out.
The detail that reframed everything
When investigators pieced together what led to the stabbing, a court document surfaced something that changed the shape of the case. Talking to herself, Mock had said she believed her mother was the devil. Her stepfather told police she’d been diagnosed with bipolar disorder, later revised to schizoaffective disorder, and had struggled for a long time with delusions and depression.
In most of the country, a statement like that opens a door: an insanity defense, the argument that someone that detached from reality shouldn’t be judged like someone who wasn’t. In Kansas, that door was bricked over decades ago. The state abolished the traditional insanity defense in the mid-1990s, one of only a small handful to do so, in a decision the U.S. Supreme Court upheld in 2020. A defendant here can’t argue she didn’t know the act was wrong. Mental illness counts only if it shows she never formed the intent the charge requires, which for first-degree murder means premeditation. A person can genuinely believe she’s killing the devil and still be convicted, as long as the state can show the act was premeditated.
What the plea erased
By pleading guilty, Mock closed the case before it opened. There would be no trial, and no jury would ever weigh whether her illness cleared the narrow bar Kansas law leaves standing. She pleaded to a single count of first-degree murder, an off-grid felony carrying a presumptive sentence of life with parole eligibility after 25 years. Sentencing is set for October 5, 2026, before Judge Faith Johnson. Her illness can still be raised there, but only to soften the sentence, never to contest her guilt.
A woman with a serious, diagnosed mental illness reached a point where she believed her own mother was the devil, and no one reached her until after Anita Avers was dead. What led her there is now something the court will never have to examine.
It’s the kind of question a jury might have turned over for days. Instead it closed in an afternoon.
