The Killer Who Smiled During His Confession

Girl Found Burning in Bathtub While Three Adults Walk Free: The Death of Victoria Martens A ten-year-old girl arrives home from school on August 23rd, 2016, and never leaves the apartment alive. Hours later, firefighters discover her body submerged and burning in a bathtub in Albuquerque, New Mexico. Three adults lived in that apartment. None were convicted of killing her. In this episode, we reconstruct the fractured timeline of Victoria Martens' final hours through conflicting confessions, forensic contradictions, and a DNA sample that belongs to someone no one can identify. The medical examiner's autopsy reveals manual strangulation and stabbing-yet the confession describes an overdose. Geolocation data places two suspects outside the apartment during the exact window of death. A third admits to severe intoxication. And a neighbor witnesses someone descending the stairs with a body wrapped in a sheet before any emergency call was made. Victim: Victoria Martens, age 10 Date: August 23-24, 2016 Location: Arroyo Villas apartment complex, Albuquerque, New Mexico Status: Three convicted; killer unconfirmed - Autopsy found no drugs or alcohol in Victoria's body, contradicting the mother's confession that she died from an overdose. - Geolocation data places the two adult suspects outside the apartment during the exact 30-minute window when the medical examiner determined death occurred. - An unidentified male DNA sample was found on Victoria's back that does not match any of the three convicted individuals or emergency responders present at the scene. - A neighbor witnessed Jessica Kelly descending the apartment stairs carrying a girl wrapped in a sheet before emergency services received any call for help.

Kevin Bacon: the date that ended in a basement and a crime that could have been avoided

The open door of the Michigan killer: The murder of Kevin Bacon On the night of December 23, 2019, Kevin Bacon went on a Grindr date and disappeared. When the police arrived at the suspect's home, he opened the door without resistance, knowing that Kevin's body was hanging from the basement ceiling. How did a man with a history of prior complaints manage to stay free long enough to commit a documented murder? In this episode, we explore how multiple failures of the police and judicial system allowed Mark Lonski to operate without consequences. We analyze the manipulative conversation on Grindr where Kevin asked, "Are you going to keep me safe?", the purchase of the knife hours before the meeting, and the deliberate plan of body dehydration. The central question remains: institutional negligence or a systematic predator that the state itself did not see coming? Victim: Kevin Bacon Date: December 23, 2019 Location: Michigan, United States Status: Life sentence without parole - Kevin asked in a message, "Are you going to keep me safe?" before descending into the basement where he was tied up and stabbed. - Lonski bought the knife at Walmart hours before the meeting and confessed to the crime via text photo to a friend in the early morning of December 24. - Multiple victims escaped from Lonski's basement years earlier; the complaints did not progress because the victims admitted to voluntary entry. - Lonski was declared mentally incompetent in 2014 for a kidnapping case, then released and never properly monitored.

Five Days, Two Bodies, a Broken System

Passersby Find Female Torso in Shopping Cart at Three AM: The Murder of Susan Leiden At 1:45 in the morning on March 3, 2022, a shopping cart abandoned at the intersection of Pennsylvania and Atlantic Avenue in Brooklyn contained a mutilated female torso. The discovery would unravel a case of homicide and dismemberment that exposed a system's fatal miscalculation about an eighty-one-year-old man released from prison. This episode explores the final days of Susan Leiden, the evidence that connected her disappearance to her neighbor Harvey Marcelin, and the pattern of dismemberment that repeated itself across four decades. How did a convicted killer released on parole strike again, and why did authorities miss the warning signs hidden in plain sight? Victim: Susan Leiden Date: February 27 - March 3, 2022 Location: East New York, Brooklyn, New York Status: Convicted - Security cameras captured Susan Leiden entering the building on February 27 at 11:40 AM; she was never seen alive again. - On March 1, Marcelin purchased a chainsaw, garbage bags, and cleaning supplies at Home Depot one day before remains were scattered. - Footage from March 2 shows Marcelin on an electric scooter transporting an amputated leg in broad daylight through Brooklyn streets. - The 2022 dismemberment pattern matched identically the 1985 murder of Ana Laura Serrera Miranda, committed while Marcelin was on parole for his first homicide.

The Monster’s Cane: How 50 Deaths Went Unpunished

Man Searches for Missing Girl He Buried Weeks Earlier: The Serial Murders of Penny Davis and the Hoffman Family A hiker discovers a human jawbone in a rural valley, and within weeks, a double homicide shakes a quiet Washington town. The man arrested had a documented history-a prison file from 1989 explicitly predicting he would become a threat to the community. No one acted on it. The investigation uncovers something far worse: the same suspect had participated in the organized searches for a missing nine-year-old girl, appearing affected and helpful, all while returning to her burial site at night. In this episode, we trace how Jack Spilman operated for months under institutional radar, balancing a functional facade with methodical predation. The evidence includes a verification phone call made from a gas station before the attack, a knife buried in a nearby dumpster, and a balaclava containing the blood of both victims-the highest concentration at the mouth opening. Psychiatric evaluations ruled out psychosis: Spilman knew exactly what he was doing and chose to do it anyway. What separates calculated evil from impulse? And how many warnings must exist before a system responds? Victim: Penny Davis (age 9), Rita Hoffman (age 31), Amanda Hoffman (age 16) Date: September 17, 1994 - April 13, 1995 Location: Eneas Valley and Wenatchee, Washington Status: Convicted - Spilman participated in daytime search efforts for Penny Davis while returning to her burial site at night to commit necrophilia - A 1989 prison file contained an explicit prediction that he would become a threat to the community, filed and archived without action - He made a verification call from a gas station to confirm Rita Hoffman was home before entering through an unlocked kitchen door at 11:30 p.m. - A balaclava discovered in his room contained blood from both murder victims, with forensic evidence suggesting ingestion during the attack Penny Davis, Rita Hoffman, Amanda Hoffman, Wenatchee Washington murders 1995, serial killer, homicide investigation, forensic evidence, psychopathy, true crime English To listen to this podcast ad-free and access premium episodes, try our subscription with a 14-day free trial at obomedia.com. © 2026 OBOMEDIA.
