December 6, 1975. Teaneck, New Jersey. After spending the night in New York City, 40-year old bar owner Wesley Diggs returns to his suburban home and discovers that his entire family has been murdered. Wesley’s 39-year old wife, Jean, and their four children – 17-year old Audrey, 16-year old Allison, 12-year old Wesley Jr. and 5-year old Roger – have each been shot multiple times and there are no signs of any forced entry. While Wesley is not considered to be a suspect, police express their belief that he might know more about the crime than he’s letting on, a claim which he denies. Over the years, a number of different theories are explored, including a botched robbery and a murder-suicide, but the investigation fails to turn any conclusive answers. On this week’s episode of “The Trail Went Cold”, we explore the unsolved murders of an African-American family, a crime which has stumped investigators for nearly 45 years.

June 11, 1930. New York City. While parked inside his car with his mistress at a secluded lover’s lane area, 39-year old Joseph Mozynski is shot to death by an unidentified assailant, who leaves Joseph’s female companion alive and gives her a cryptic note. Five days later, 26-year old Noel Sowley is fatally shot inside his car under similar circumstances and the gunman also leaves Noel’s girlfriend alive and gives her another note. The killer sends out a series of letters claiming that he is a special agent from an organization called the Red Diamond of Russia and committed the murders while on a secret mission to recover some important documents. All of his letters are signed “3X”, but in spite of an extensive police manhunt, the perpetrator is never identified. Who was the mysterious “3X” and what his actual motive for these crimes? This week’s episode of “The Trail Went Cold” chronicles the bizarre saga of the “3X Murders” which have remained unsolved for 90 years.

January 31, 1993. Amarillo, Texas. The wife and daughter of 39-year old David Lewis return home from a weekend trip and discover that David is not at the house and has left his watch and wedding ring behind. David’s abandoned car is soon discovered in the downtown area with his identification and many other personal items inside, but even though investigators turn up a series of bizarre clues, including a pair of plane tickets purchased under David’s name, they are unable to find him. Eleven years later, David is positively identified as a John Doe who was fatally struck by a vehicle on a highway in Yakima County, Washington just over 24 hours after he originally went missing. But how and why did David wind up nearly 1,600 miles from his home? Did he travel there voluntarily or was he abducted? Was David’s death a random hit-and-run accident, an elaborate suicide, or an intentional homicide? This week’s episode of “The Trail Went Cold” explores the truly bizarre unexplained death of David Lewis, one of the most baffling mysteries we’ve ever covered.

June 12, 1962. Worthington, Minnesota. 20-year old Marlys Gross gives birth to a baby daughter named Mary Agnes, but is told by the hospital staff that the child died shortly after she was born. Mary Agnes is given a funeral and buried in a grave, but months later, Marlys is mailed a photograph of an unidentified family holding a baby whom she believes is her daughter. Over the next three decades, Marlys would discover a number of suspicious discrepancies to make her believe that Mary Agnes is still alive, so she petitions to have her gravesite exhumed in 1996. While skeletal remains of a deceased child are found, DNA testing reveals that they do not belong to Mary Agnes. Did the hospital orchestrate a cover-up in order to perform a black-market adoption and sell Mary Agnes to another family? If so, then whose remains were buried in Mary Agnes’ grave? This week’s episode of “The Trail Went Cold” explores a very bizarre and complicated mystery about the disappearance of a newborn infant.
