Criminal Investigations, Case Reviews & Safety Consulting Across Arizona.
Highland Investigations is an Arizona investigative firm built on 48 years of combined law-enforcement experience in homicide and violent crime. We conduct criminal investigations, independent case reviews, crime scene analysis, evidence and report review, and witness interviews for attorneys, law firms, agencies, businesses, and private clients. We also deliver in-depth security and safety consulting, drawing on the same investigative background to assess risk and strengthen protection.
Serving Tucson • Phoenix • East Valley • Prescott • Northern Arizona
Investigators First
Highland Investigations is led by two career investigators whose work centered on homicide and violent crime with the FBI Violent Crimes Task Force and Arizona DPS. That investigative background drives everything we do — criminal investigations, case reviews, crime scene analysis, evidence and report review, and interviews — for attorneys and law firms, agencies, businesses, and private clients. Security and safety consulting rounds out the practice.
