The Warner trial in Adrian, Michigan resumed with testimony from a Michigan State Police K-9 handler detailing the early searches of the Munger Road property. The testimony focused on what cadaver and tracking dogs can and cannot detect, with the K-9 handler explaining that unless blood, bone or tissue is present outside a container, a cadaver dog would likely not be able to detect remains sealed inside. The court also heard from an FBI agent who executed a search warrant at the property months later, finding handwritten notes and journals in a vehicle associated with the defendant. Prosecutors are building a timeline of the investigation using digital evidence like cell phone records and surveillance footage.

Why it matters

This case highlights the challenges law enforcement faces in conducting thorough searches, especially when dealing with sealed containers or limited physical evidence. The testimony about the capabilities and limitations of K-9 units, as well as the reliance on digital data, provides insight into modern investigative techniques and the evolving role of technology in criminal cases.

The details

Trooper Jack Taft of the Michigan State Police testified about his initial K-9 searches of the Munger Road property in April 2021, using both a narcotics/tracking dog and a cadaver dog. Taft explained that cadaver dogs are trained to detect human remains, but would likely not be able to alert on remains sealed inside a container without any exposed blood, bone or tissue. FBI Special Agent Henrik Impola then described a more extensive search of the property in October 2021, where his team found handwritten journals and notes in a vehicle associated with the defendant, Dale Warner. Prosecutors displayed excerpts of these notes, which referenced tracking locations, arguments, and the days following the victim's disappearance. The court also heard from Detective Sgt. Scott Singleton, who reviewed surveillance footage from the property and discovered a tank that prompted further investigation.

  • On April 27, 2021, Trooper Taft first responded to the Munger Road property with his K-9 units.
  • In October 2021, the FBI executed a search warrant at the Munger Road property.
  • In August 2024, the victim's body was located, prompting investigators to revisit earlier surveillance footage and evidence.
