Former TV Anchor Pleads Guilty to Killing Her Mother Over One Twisted Belief

A Missouri TV anchor was found covered in her mother's blood last Halloween.

Angelynn Mock just walked into a Wichita courtroom to answer for it.

What she told investigators about her mother that day is almost impossible to believe.

Mock Told Investigators She Believed Her Own Mother Was the Devil

Angelynn Mock, 47, spent 2011 to 2015 anchoring the morning news for Fox 2 in St. Louis and later worked at KOKH Fox 25 in Oklahoma City.

By the time of her arrest, she had left television entirely and was working in sales for a data management software company.

Last Halloween, police responding to a Wichita home found Mock outside with cuts on her own hands.

Her 80-year-old mother, Anita Avers, had been stabbed multiple times as she sat in her own bed, and died at the hospital a short time later.

Investigators found the scene surrounded by multiple knives and a cheese grater, all allegedly used in the attack.

A neighbor, Alyssa Castro, says Mock ran up to her car covered in blood, begging to use a phone to call 911.

According to dispatch records, Mock told the operator she had stabbed her mother to save herself.

Prosecutors charged her with first-degree murder within hours and held her on a one million dollar bond.

According to the probable cause affidavit, Mock later told investigators, "I had to kill her, she wasn't going to stop," and made statements indicating she believed her own mother was the devil.

That claim sent the case down an unusual path.

A judge ordered a competency evaluation weeks after the charge, and by January a judge had ruled Mock unfit to stand trial at all, sending her to Larned State Hospital for treatment.

That finding could have parked the case indefinitely.

Doctors restored her to competency by July, and this month, nearly ten months after her mother's death, Mock pleaded guilty rather than force a trial.

She faces a presumptive sentence of life in prison, with parole eligibility after 25 years, when a judge formally sentences her on October 5.

A Career Behind the Anchor Desk Ended in a Wichita Courtroom

Mock was not some anonymous suspect.

She spent years on air in local television, the kind of familiar face viewers invited into their living rooms every night, before she quietly left the business altogether for a desk job in software sales.

That familiarity is exactly why this case cut so deep in Missouri and Kansas news markets when the charges first came down.

Neighbors and former colleagues describe a woman who seemed ordinary right up until the moment police say she picked up a knife against her own mother.

Prosecutors did not need a jury to secure justice here.

Mock's guilty plea locks in a life sentence and spares the family the added trauma of reliving the crime scene testimony in open court.

An October sentencing hearing will make it official, but the plea itself already guarantees she will not walk free anytime soon.

This Time the Competency Fight Did Not Become an Escape Hatch

Here is what actually fires people up about this case: an 80-year-old woman is dead, stabbed by her own daughter in her own home on a night meant for trick-or-treaters, and the explanation offered up is a delusion about the devil.

That is not an excuse.

Anita Avers went to bed in her own home and never woke up, because the daughter she raised decided she was something to be destroyed.

Cases built on an incompetency finding have a way of quietly stalling for years while families wait for answers that never come.

This one did not stall, because doctors and prosecutors kept pushing for ten straight months until Mock was competent enough to answer for what she did, and she ultimately admitted it herself instead of hiding behind the diagnosis permanently.

Mock gets to spend at least the next 25 years in a cell thinking about that, with no guarantee she ever walks out after.

Anita Avers does not get a second chance, and the only reason this case ended in a guilty plea instead of an indefinite hold at a state hospital is that nobody let the competency fight become the final word.
