"On a September night in 1966, Dianne Keidel met a friend for a drink, and afterward, she disappeared." Investigators were unable to determine if Dianne was the victim of foul play, or if she couldn't face the responsibilities of being a single mother with four young children . That question was answered twenty-seven years later, when her daughter came forward with a fantastic tale of something she remembered seeing when she was only five-years-old. Could ground-penetrating radar and forensic anthropology help solve the mystery that haunted a young child all the way into adulthood? This episode covers the disappearance of Diane Kaidel, the tragic deaths of her children, and the eventual revelation of her murder by her husband Jean Kaidel . In 1993, after 27 years, Lori provided a written statement to police detailing the murder she had witnessed . This led to an investigation that uncovered Diane's remains buried under concrete. Jean Kaidel was arrested and convicted of murder in 1995, largely based on Lori's testimony .

"It's alright to kill someone these days, isn't it? Think I might do that." Adam Whelehan tweeted this days before he butchered his ex-girlfriend, Natalie Jarvis, in a country lane in Kent.
The 23-year-old BT apprentice lured Natalie, 23, to his car on October 3, 2012, under the pretense of discussing their relationship. But he had a friend hiding in the boot. When she got out, Whelehan slit her throat with a multi-tool, inflicting 20 stab wounds to her neck as she pleaded for him to call her mother—he broke her phone in front of her. The attack left a trail of blood stretching 150 metres. Whelehan claimed self-defense, but the jury convicted him of murder. He received a life sentence with a minimum of 26 years, with the judge calling his actions "callous, savage and premeditated."

The rape case seemed open and shut. The victim identified Edward Honaker in a lineup, and he was sentenced to three life terms in prison. But Honaker never stopped insisting he was innocent — and that his alibi was proof. Years later, an attorney listened to his letters and agreed to pay for DNA testing. The semen found on the victim did not match Honaker. The victim later admitted another man had been in her life at the time, and the DNA didn't match him either. After serving ten years, Honaker was exonerated. The episode is a powerful look at the flaws of eyewitness testimony and the impact of forensic science on justice.

"He strangled two women and left their bodies in industrial areas. A cigarette paper and a chewed-up nicotine habit helped convict him."
James Michael Randall was a window installer from Florida who killed prostitutes Wendy Evans and Cynthia Pugh in 1995 and 1996 [citation:3]. He had a history of choking his sexual partners and once told his girlfriend: "I hurt others so that I would not hurt you" [citation:11]. He led police on a high-speed chase and fled on foot before being captured four days later [citation:3]. Randall initially received a death sentence, but the Florida Supreme Court reduced it to life imprisonment in 2000 [citation:3]. His crimes were featured on *Forensic Files* and *World's Most Evil Killers* [citation:1][citation:7].

"In 1993, young Navajo Indians in the Four Corners area were dying at an alarming rate. More than 20 people lost their lives to a mysterious illness that left health officials baffled."
This episode follows the CDC's investigation into the deadly outbreak, which initially struck Merrell Bahi and Florina Woody, a young couple who left behind an infant son. Tribal medicine men provided a critical clue, leading investigators to identify a previously unknown strain of hantavirus from deer mice feces. The episode explores the collaboration between traditional healers and modern forensic science to solve one of the most puzzling medical mysteries in American history [citation:1][citation:4].

"The rope was made of garbage. The man who used it wore a uniform. And the trail of bodies stretched from Nebraska to Maine."
An 11-year-old boy's murder in Portland links to a series of child killings across state lines. The only clue: a unique "junk rope" made from discarded fibers. When police connect the case to an Air Force enlistee with a disturbing signature, forensic science and psychological profiling finally break a 116-day manhunt. [citation:2][citation:4][citation:6]

🔪 "He reported her missing weeks later. He appeared on TV. He even smiled." A doctor who dismembered his wife in a shed, destroyed evidence, and never revealed where he hid her body.
Hassan Al Shatanawi murdered Laura May in 1993[citation:1]. He bought an allotment shed, killed her, and paid a worker to burn it[citation:5]. Instead, the shed was sold, preserving DNA evidence[citation:1][citation:8]. Shatanawi was convicted of murder in 1994 and sentenced to life. He was deported in 2013 without ever revealing her remains[citation:3].

🛁 "He drew her a bath. He went for a jog. He came back to find her dead." Julie Post's drowning seemed accidental—until investigators noticed a broken towel ring and a husband who talked too much.
A real estate salesman, a $700,000 life insurance policy, and a second autopsy revealing 36 bruises turned a tragedy into a murder case [citation:1][citation:8][citation:11]. Prosecutor Dee Joyce-Hayes spotted the tell: Ed Post introduced himself to a doorman and explained his jogging route—an alibi no one asked for [citation:2]. Convicted in 1989, he later pleaded guilty to second-degree murder.

"Mom, do me a favor. Take this down to the mailbox." Those were the last words eight-year-old Vicki Lynne Hoskinson ever spoke to her mother [citation:1][citation:7]. She vanished on September 17, 1984, in Tucson, Arizona [citation:3][citation:6]. Her pink bicycle was found abandoned nearby. A tiny speck of paint on a suspect's bumper—and an even tinier trace of nickel—would lead detectives to her killer, Frank Jarvis Atwood [citation:1][citation:7][citation:11]. Atwood had a criminal history of lewd behavior and kidnapping [citation:7][citation:10]. He was arrested, convicted, and sentenced to death [citation:10].

"His charred body was found in a stolen van. His loose lips led police straight to his door."
In this episode, we examine the case of Kenneth Ray Jackson, a 25-year-old who brutally murdered 50-year-old Cuc Thu Tran in 2007. He raped and fatally stabbed the Vietnamese immigrant as she jogged, then set her body ablaze [citation:10]. A jury convicted him, and the judge called the crime "shockingly evil" [citation:10][citation:15]. Initially sentenced to death, that penalty was later overturned, and he was re-sentenced to life in prison [citation:15].
