Episode: Doctor Bludgeoned to Death—New Twist in Teresa Sievers Case

Host: Katie Ring

Date: November 13, 2025

Episode Overview

This episode dives deep into the chilling 2015 hammer murder of Dr. Teresa Sievers and the dramatic new developments shaking up the case a decade later. With her husband Mark Severs on death row for hiring two men—his best friend Curtis Wright and accomplice Jimmy Ray Rogers—to kill her, the case seemed closed. But now, Rogers has testified with a strikingly different account of the events, potentially upending everything previously believed and possibly offering Mark a shot at a new trial. Host Katie Ring carefully unpacks the evidence, the personalities involved, and what this latest twist could mean for justice.

Key Discussion Points & Insights

1. Background: Who Was Teresa Sievers?

• [05:34] Teresa is described as a dedicated physician, loving mother, and passionate advocate of holistic medicine.
  • Valedictorian, Ross University School of Medicine, residency at University of Florida.
  • “She dedicated her life to helping others... she believed that everyone should have the ability to take control of their own health.” —Katie Ring, (07:14)
  • Ambition: Wanted to host her own TV show to educate more people.

2. The Marriage and Hidden Tensions

• Teresa meets Mark Sievers, a Missouri nurse; they marry quickly and run a holistic practice together.
• Financial and marital problems develop; money issues worsen with a $33,000 IRS lien.
• Mark claims they were swingers; jealousy arises when Teresa shows interest in Curtis Wright, Mark's best friend since childhood.
  • “Mark is not okay with the idea of Teresa sleeping with Curtis, and he starts becoming insecure...” —Katie Ring, (09:18)

3. The Murder Plot is Hatched

• Mark and Curtis plan to kill Teresa for a $4.4 million life insurance payout.
• Curtis secretly pulls in another accomplice, Jimmy Ray Rogers (“the Hammer”).
  • “When Curtis hears this evil plan, he is totally on board, and he's actually more than just okay with it. He wants in.” —Katie Ring, (11:42)

4. The Crime

• Timeline

  • June 27-28, 2015: Curtis and Jimmy drive from Missouri to Florida, buy supplies (garbage bags, lock-picking kit, black clothes) at Walmart, and wait at the Seivers’ home.
  • Teresa returns home; Curtis attacks her with a hammer, Jimmy joins in, bludgeoning her 17 times.
  • They flee back to Missouri.

• “As they approach her, Teresa asks her husband's best friend one simple question. Why? Curtis doesn't reply. Instead, he hits Teresa in the head three times...” —Katie Ring, (15:10)

5. Investigation and Break in the Case

• Suspicion soon falls on Mark due to inconsistent stories, suspicious behavior (telling his mom not to set the alarm), and financial motives.

• Break comes from an anonymous call about Curtis' sudden trip to Florida—the tip leads to GPS evidence and Walmart security footage.

• Jimmy's girlfriend, Taylor Shoemaker, gives crucial information, including Jimmy's confession and evidence disposal route.

• Memorable Moment [21:16]:

  • “Taylor says she became suspicious of him after that and tells police that she confronted Jimmy directly... he even laughed when he told Taylor that the murder weapon was a hammer to match the nickname he had given himself.”

6. Arrests, Trials, and Sentences

• By late August 2015, all three men are in custody.

• Physical evidence (blue fibers, jumpsuit, GPS data), text records, and confessions all point to a coordinated murder for hire.

• Curtis testifies against Jimmy, then Mark, receiving a lesser sentence (max 25 years). Jimmy gets life, Mark is sentenced to death.

• “The jury takes Curtis at his word, and they find Mark Sievers guilty of first degree murder.” —Katie Ring, (24:23)

7. A Decade Later: The Case is Flipped

• October 2025: Post-conviction relief hearing.
• Jimmy Ray Rogers' Shocking New Testimony [25:03]:

  • Claims there was no murder plot, Mark is innocent; Curtis (not Mark) killed Teresa in a fit of rage after an argument.

  • “Jimmy completely flips the narrative... He says there was no premeditated plan to kill her and that Mark is totally innocent.”—Katie Ring, (25:04)

  • Rogers says he only went to Florida to help with painting/computer work, watched Curtis attack Teresa, and claims Curtis threatened to kill him if he told anyone.

  • Rogers also alleges a longstanding affair between Curtis and Mark, implying jealousy was Curtis' true motive.

8. Host's Analysis and Remaining Questions

• Katie expresses skepticism about Jimmy's new story, hinting at possible manipulation or payoff.

  • “With the timing of this all, it's sounding to me like Mark maybe paid someone off... Telling his mom not to set the security alarm, telling Curtis about the $4 million life insurance policy and his cryptic text after seems a little sus.” —Katie Ring, (26:10)

• Notes the continued grief of Teresa’s family, her daughters’ care, and a book written in Teresa’s memory.

Notable Quotes & Memorable Moments

• On Teresa’s character:

  • “She was just under 5ft tall, but is described as a spitfire who was willing to do anything she could to help others.” —Katie Ring, (06:00)

• On Mark’s reaction after Teresa’s death:

  • “Mark is not only sobbing uncontrollably, but he's crying out for Teresa and hitting himself in the face. To the detectives, it all seems a little overdramatic. It's giving bad acting.” —Katie Ring, (17:45)

• On the new twist:

  • “He [Jimmy] says there was no premeditated plan to kill her and that Mark is totally innocent.” —Katie Ring, (25:04)

• On possible motives and truth:

  • “I highly doubt Curtis is going to threaten to kill a guy who calls himself the Hammer, and that a guy who calls himself the Hammer would respond well to that or even be intimidated by that threat at all.” —Katie Ring, (26:13)
