Forensic Files

This episode of ID's Who Killed Angel Harris explores the harrowing true story of Diane Keidel, a woman who disappeared in 1966 and was not found for twenty-seven years. For decades, her husband, Gene Keidel, maintained that she had abandoned her four children to run away with a lover. The narrative follows the survival of her daughter, Lori, through a subsequent house fire that claimed the lives of two siblings, and the eventual revelation of a dark family secret. The investigation details how a written statement from Lori in 1993 led detectives to use ground-penetleating radar to uncover remains beneath a concrete patio. Through forensic anthropology and skull photograph superimposition, investigators identified the remains as Diane Keidel. The episode concludes with the conviction of Gene Keidel for the murder of his wife, based on the eyewitness testimony of his daughter.

This episode explores the harrowing case of Terry Henson, a North Carolina mother who was arrested and charged with murder and arson following a 1996 house fire that claimed the life of her 17-month-old son, Joshua. Initially suspected by investigators due to her behavior and personal history, Terry faced the possibility of the death penalty after local authorities concluded the fire was intentionally set. The investigation into the fire's origin was later challenged by Dr. Gerald Hurst, a chemist who identified evidence of electrical malfunction and structural issues caused by recent hurricane damage. The narrative details the scientific breakdown of how an electrical arc in the attic likely ignited the paper insulation, contradicting the prosecution's theory of an upward-burning arson fire. Through the work of independent investigators, the charges against Terry were eventually dropped, though the case highlights significant flaws and biases within traditional arson investigation practices.

This episode investigates the 2008 murder of Jenna Verholen, a college student at Blinn College in Bryan, Texas. After being found dead in her apartment with signs of manual strangulation, investigators faced a complex web of suspects, including her boyfriend, a neighbor seen acting suspiciously, and a maintenance man who had previously entered her apartment uninvited. The investigation pivoted on forensic DNA evidence recovered from Jenna's fingernails and clothing. Through a massive DNA dragnet and the tracking of three primary persons of interest, authorities eventually linked the crime to Jeremy Rosser, a former maintenance worker. The episode details the forensic breakthroughs and the eventual conviction of Rosser, who was sentenced to 55 years in prison.

In the quiet town of Waseca, Minnesota, the 1999 murder of twelve-year-old Callie Jo Larson initially left investigators with a cold case and no usable forensic leads. While early searches for fingerprints and blood DNA yielded only results from family members, a series of local burglaries eventually led police to Lorenzo Sanchez. The investigation pivoted when stolen CD cases were discovered in Sanchez's home, containing both the victim's unique fingerprint and a strand of her hair. Through advanced mitochondrial DNA testing on hairs found at the crime scene, investigators were able to link the evidence to the Sanchez family. Despite the complexity of shared maternal DNA among siblings, the lack of an alibi for Lorenzo, combined with a recorded prison conversation where he attempted to frame his brother, led to his guilty plea. The case serves as a profound example of how microscopic trace evidence can solve even the most stalled homicide investigations.

The episode investigates the 1993 murder of 13-year-old Dario Ciccalecchia in a small Swiss village. After the boy went missing while fishing, his mutilated body was discovered in a cornfield, leaving investigators with no traditional forensic evidence like hair or fibers. The case took a scientific turn when researchers utilized the study of diatoms—microscopic algae found in the boy's lungs and on his sneakers—to pinpoint the exact body of water where the drowning occurred. The investigation eventually linked the crime to Roland Keebler, a psychiatric nurse arrested in France for a separate assault. By analyzing microscopic debris from the pedals and carpet of Keebler's car, forensic experts identified the same specific diatom species found at the murder site. This breakthrough led to a full confession and revealed a pattern of violence that included a second unsolved murder.

In 1993, South Florida experienced a violent crime spree targeting tourists, characterized by 'bump and rob' tactics and fatal assaults.

The investigation relied on advanced forensic odontology, using dental impressions and specialized photography to link suspect Stanley Cornett to the crime. The narrative details the technical process of bite mark analysis, including the use of plaster models and light spectrums to identify dental patterns. Despite Cornett's attempts to use an alibi and legal delays, the combination of victim identification and forensic evidence led to his life sentence. The episode concludes with the impact of these crimes on Florida tourism and Helga Lust's subsequent work in victim advocacy through her group, Witness Justice.

In 1979, Diana Green was brutally assaulted in her California apartment, an attack that resulted in the death of her unborn child and left her in a coma. Her husband, Kevin Green, was subsequently convicted of the crime based on her eyewitness testimony, despite his claims of innocence and the presence of a mysterious figure outside their home. The case remained closed for sixteen years until advancements in DNA technology and a confession from an inmate known as the 'bedroom basher' revealed the true perpetrator. The episode explores the complexities of memory, the limitations of forensic science in the late 1970s, and the eventual exoneration of Kevin Green. Through interviews and archival accounts, the narrative details how a series of unsolved rape-murders were linked to Gerald Parker, whose DNA match ultimately corrected a profound miscarriage of justice.

This episode investigates the death of Ari Squire, which was initially believed to be an accidental garage fire but was later revealed to be a calculated murder-suicide.

The investigation eventually led to the discovery of Squire's body in a Missouri motel, where he died by suicide to avoid life imprisonment. The aftermath includes a wrongful death lawsuit and investigations into Denise Squire's potential involvement in the murder plot.

In the small town of Navasota, Texas, a prominent community leader and funeral director, Lonnie Turner Sr., was found shot to death in his bedroom. The investigation initially focused on his son, Lonnie Jr., due to suspicious behavior, gunshot residue on his hands, and a 9mm handgun found under his mattress that matched the murder weapon. However, forensic DNA analysis of a homemade mask found near a nearby creek provided a breakthrough, eventually linking the crime to the victim's godson, James White. The case involves complex layers of family dynamics, including conflicting accounts from the victim's son and brother, as well as allegations of a conspiracy. While White eventually confessed to the shooting but claimed he was coerced by Lonnie Jr., physical evidence and cell phone records supported the son's alibi. The episode explores how forensic science ultimately resolved a case filled with contradictory testimonies and deep-seated community suspicion.

This episode of Serial Killers and Murderous Minds investigates the 1982 abduction and murder of 11-year-old Krista Lee Harrison in Marshallville, Ohio. The investigation centered on highly unusual orange trilobal polyester carpet fibers found at the crime scene, which also appeared in a previous murder case involving Tina Harmon. As investigators faced the possibility that a serial killer was active in the region, they utilized forensic evidence—including specific plastic packaging and cardboard from Sears Roebuck & Company van seat shipments—to track potential suspects. The case reached a breakthrough following the kidnapping and escape of a gas station manager, whose survival provided the identity of Robert Anthony Buell. Through meticulous forensic links involving carpet fibers, clothing patterns, and paint samples, prosecutors were able to secure a death sentence for Buell, while simultaneously uncovering evidence that led to the exoneration of a previously convicted man.

An investigation into a series of execution-style killings in North Carolina reveals a connection between the murders of Victor Gunnarsson and Catherine Miller.

In 1995, 14-year-old Jenna Mauser disappeared from her home, only for her body to be discovered days later in a roadside ditch. The investigation initially faced a lack of physical evidence, as there were no DNA samples or signs of a struggle within the home. However, a combination of forensic botany and advanced photogrammetry eventually linked her stepfather, Doug Mauser, to the crime. Investigators utilized plant biology to identify specific yellow star thistle found under the suspect's car that matched the development of plants found near the body. Furthermore, 3D modeling of post-mortem pressure marks on the victim's skin allowed experts to recreate the exact pattern caused by a seat belt buckle and carpet edge in the suspect's vehicle. The episode details the reconstruction of the crime and the forensic breakthroughs that led to a murder conviction.

In 1988, the death of popular Durham High School teacher and coach Russ Steger was initially ruled an accidental shooting. His wife, Barbara Steger, claimed the .25 caliber pistol under his pillow discharged while she was attempting to remove it. However, forensic evidence, including bullet trajectory, trigger pull tests, and the absence of gunpowder residue, began to contradict her account. As investigators delved deeper, they uncovered a pattern of suspicious deaths involving Barbara's previous husband and discovered evidence of financial fraud, including forged signatures and a $170,000 life insurance policy. The case was ultimately solidified by a chilling audio recording made by Russ Steger himself just days before his death, in which he expressed fear for his life and suspicion regarding his wife's motives.

This episode of Disturbed True Horror Stories explores the chilling case of Marie Robards, a high-achieving student in Texas who orchestrated what appeared to be the perfect crime. Following the sudden death of her father, Steve Robards, from what was initially ruled a natural heart attack, a hidden truth began to emerge through a Shakespearean connection and a friend's growing torment. The investigation eventually utilized advanced gas chromatography to uncover a massive, lethal dose of a rare metallic poison stolen from a high school chemistry lab. The narrative details the forensic breakthrough that linked the stolen substance to the crime, the subsequent confession, and the trial that captivated the public. Driven by a desire to reunite with her mother, Marie's actions led to a conviction and a twenty-seven-year prison sentence, leaving behind a legacy of a calculated crime born from the complexities of family upheaval and teenage resentment.

This episode investigates the investigation into Archbishop Valerian Trifa, a high-ranking Romanian Orthodox Church official in the United States accused of being a Nazi war criminal.
