Dateline True Crime Weekly: Justice Delayed and New Investigations

This episode of Dateline True Crime Weekly covers a series of high-profile criminal investigations, ranging from cold cases resolved by cutting-edge forensic technology to ongoing searches for missing children.

The Scottsdale Murder: DNA and Legal Deadlocks

In 2015, Allison Feldman was found beaten to death in her Scottsdale, Arizona home. Investigators initially struggled, interviewing nearly 500 people and collecting DNA from over 70 suspects without a match. The case remained cold for three years until police utilized "familial testing," a technique involving government databases that identified a relative of a convict named Mark Mitchum. This led to the arrest of his brother, Ian Mitchum.

As the case approached trial, the defense challenged the admissibility of the DNA evidence, arguing that the blood sample collected during Mitchum’s prior DUI arrest was used in violation of his Fourth Amendment rights. Although the trial judge initially agreed, the Arizona Supreme Court eventually ruled the evidence admissible. As the trial finally begins, the defense has pivoted to implicating an alternative suspect—Feldman’s former pharmacist—highlighting the complex evidentiary battles that have delayed justice for a decade.

Illinois: The Slover Case and the Innocence Project

In 1996, the disappearance and subsequent dismemberment of Karen Hearn Slover led to the conviction of her ex-husband, Michael Slover Jr., and his parents. Despite the 2002 guilty verdict, the Illinois Innocence Project has recently challenged the conviction. They claim that new DNA profiles found on duct tape near the crime scene and a bloody fingerprint on a bridge railing do not match the Slover family. While the Illinois State Police have refused to enter this "random evidence" into the CODIS database—citing concerns over the chain of custody—a hearing is set for the new year to determine if the evidence warrants a re-examination of the case.

Dateline Roundup: Birchmore, Koberger, and Landeros

  • Sandra Birchmore: Federal prosecutors have hit former police officer Matthew Farwell with an additional charge regarding the death of Birchmore’s unborn child, claiming he killed both the victim and her fetus. Farwell, who is accused of staging the scene as a suicide to cover up an illicit relationship, faces a potential mandatory life sentence.
  • Brian Koberger: The Idaho murder suspect returned to court for a restitution hearing regarding funeral expenses for his victims. Publicly released documents have also provided chilling new details, including images of the knife sheath left at the crime scene.
  • Jorge Rueda Landeros: A jury has found Landeros guilty of the second-degree murder of American University professor Sue Ann Markham, closing a 15-year-old case involving insurance fraud and a fugitive who had been hiding in Mexico.

Missing in America: The Case of Relisha Rudd

The episode concludes with a spotlight on the 2014 disappearance of eight-year-old Relisha Rudd from a Washington, D.C. homeless shelter. The Black and Missing Foundation has released a documentary, The Vanishing of Relisha Rudd: A Cold Case Re-Examined, to bring attention to the systemic failures that allowed 18 days to pass before she was officially reported missing. The investigation remains haunted by the suicide of Khalil Tatum, the shelter janitor seen in surveillance footage with Rudd, who took his own life before providing answers. Founders Derrica and Natalie Wilson emphasize that children in poverty are disproportionately vulnerable, and they continue to urge the public to "see something, say something" to help close this tragic chapter.
