In the world of investigations, few cases carry the weight of a death investigation. For Beau Dietl & Associates, New York’s leading firm in private investigation and risk management, the stakes couldn’t be higher and without a statute of limitations…
Often, by the time we’re brought in, these cases have been classified as a “CUPPI” (Circumstances Undetermined Pending Police Investigation) case, meaning law enforcement couldn’t, or wouldn’t, provide answers. Families feel the system has let them down. Our mission is to bring both closure and clarity to those who need it most.
Death investigations share surprising similarities with complex corporate investigations. Both require meticulous attention to detail, a deep understanding of human behavior, and a relentless pursuit of facts that others might have missed. Just as in fraud cases where clients are often left with unresolved questions and financial devastation, families in death investigations are left with the pain of unanswered questions about a loved one’s final moments.
BDA, established in 1986 on the success of Beau’s career in the NYPD as a premier detective, is staffed for and equally skilled in all of the 5 main areas of death investigations:
Scene Investigation
This involves a comprehensive examination of the location where the death occurred. Investigators collect evidence, document the scene through photos and sketches, and observe any relevant environmental details. They look for signs of struggle, the position of the body, and any potential clues that could indicate how the death occurred, such as weapons, medications, or personal items.
Collection of Physical Evidence
Investigators gather all physical evidence that could shed light on the circumstances surrounding the death. This may include biological samples, fingerprints, bloodstains, weapons, and items from the scene that could contain DNA or other forensic information. Proper evidence handling is crucial to avoid contamination and preserve its integrity for analysis.
Autopsy and Medical Examination
A forensic pathologist performs an autopsy to determine the cause and manner of death, such as homicide, suicide, accidental, natural, or undetermined. The autopsy includes an external and internal examination of the body, toxicology tests, and analysis of injuries. Findings from the autopsy provide vital information about the time, mechanism, and cause of death.
Background Investigation
Investigators gather background information on the deceased, including their medical history, mental health, lifestyle, and relationships. They interview family, friends, and colleagues to understand the decedent’s habits, potential conflicts, or any recent changes in behavior. This contextual information can help establish a motive, identify suspects, or provide insights into whether the death was accidental or intentional.
Case Analysis and Reconstruction
After collecting all the data, investigators analyze the evidence, autopsy findings, and background information to reconstruct the events leading to the death. They piece together the timeline and assess how different factors fit into the case. This analysis may involve collaboration with forensic experts and other professionals to arrive at a conclusion about the circumstances of the death. If the case involves criminal activity, investigators work closely with law enforcement to pursue justice.
Each of these components is essential for establishing the cause, manner, and circumstances of death in a thorough and reliable death investigation.
Recently, we undertook a case involving Zack Freeling’s homicide—a case initially stalled and left without resolution. Through rigorous investigation, innovative techniques, and unwavering commitment, we helped law enforcement and Zack’s family finally understand the truth behind his tragic death. The results of this investigation, recently featured in The Washington Post, underscore the unique skillset Beau Dietl & Associates brings to complex cases.

At Beau Dietl & Associates, we take pride in our ability to dig deeper, deliver answers, and bring closure to those failed by “the system.”
