MrBallen Podcast: Strange, Dark & Mysterious Stories Episode: Bad Blood (Podcast Exclusive Episode) Release Date: July 7, 2025

Introduction

In this exclusive episode of the MrBallen Podcast, Ballen Studios delves into the harrowing true crime story of Lisa Techle's tragic murder. Set against the backdrop of rural Iowa, this narrative unravels the complexities of neighborly tensions, investigative oversights, and the ultimate revelation of betrayal within a family.

Background

Setting the Scene (00:00 - 03:13)

The story begins in March 2012, introducing Lisa Techle and her husband Seth, both dedicated corrections officers working in nearby counties. Their lives take a sinister turn as they navigate the challenges of impending parenthood alongside escalating tensions with their neighbor, Brian Tate—a 57-year-old Vietnam War veteran grappling with PTSD and schizophrenia.

Quote:

“Being a corrections officer was not exactly exciting or glamorous for either Lisa or Seth, but it was steady and gave both of them a real shot at eventually moving up to deputy positions.” (03:13)

The Crime

A Tragic Morning (05:23 - 14:48)

On the morning of May 26, 2012, Deputy Martin Wonderland responds to a distressing call about a shooting at Lisa and Seth's trailer home. Arriving at the scene, Wonderland discovers Lisa brutally murdered alongside her unborn child. The initial evidence—primarily the presence of a pistol too small to have caused the fatal wounds—raises more questions than answers.

Quote:

“Lisa lay motionless in the bed. Her chest had been torn open by massive gunshot wounds.” (08:45)

Investigation

Focus on the Feud (14:48 - 15:50)

As the investigation unfolds, suspicion naturally falls on Brian Tate due to his known mental health struggles and history of accusing the couple of vandalism. Todd Caldwell, Lisa's father and a deputy himself, initially stands firmly behind Seth, trusting in his integrity. However, mounting evidence begins to shift perspectives.

Quote:

“Brian was a neighbor that kept calling Todd's office to accuse Seth and Lisa of vandalizing his property.” (10:30)

Undisclosed Evidence and Revelations

Further complicating the case, a shotgun matching the murder weapon's caliber is discovered near Seth and Lisa's trailer, registered to one of Seth's acquaintances. Additionally, a seemingly innocuous peanut butter and jelly sandwich found at the crime scene later becomes a pivotal piece of evidence, suggesting the presence of another individual at the time of the murder.

Quote:

“The shotgun was not Seth's, but it was registered to one of Seth's friends, who told detectives he had left it with Seth for safekeeping.” (12:15)

Trials and Tribulations

First Two Trials: A Struggle for Truth

Seth faces two mistrials due to hung juries, each bringing forward new facets of the investigation. Defense attorneys argue police negligence, pointing out procedural errors and overlooked evidence that could exonerate Seth. Despite these efforts, public perception remains skewed against him, fueled by relentless media scrutiny of Brian Tate's mental instability.

Quote:

“The defense presented the half-eaten sandwich as emblematic of all the questions the police could not answer.” (18:00)

Third Trial: Unveiling the Truth

In a dramatic turn during the third trial, a crucial witness emerges, revealing that Seth had orchestrated the feud with Brian to divert suspicion. This revelation uncovers Seth's affair with a co-worker, Rachel, providing a clear motive for him to eliminate Lisa and manipulate the investigation to his advantage.

Quote:

“Seth had goaded Brian into a feud that made him look crazy and dangerous.” (22:45)

Conclusion

Verdict and Aftermath

Ultimately, Seth is found guilty of first-degree murder and non-consensual termination of a human pregnancy, receiving a life sentence without parole. The case leaves a lasting impact on those involved, highlighting the dangers of unchecked personal motives and flawed investigative processes.

Final Reflection:

“Seth was alone. But while the state swiftly moved toward a trial against Seth, the media was not ready to let Brian Tate go as a suspect.” (20:50)
