Tharsis Investigations LLC is owned and operated by Kevin E. Kubitskey — retired Pima County Sheriff's Sergeant and U.S. Marine Corps Reconnaissance Marine and Scout Sniper veteran, with over 30 years of combined law enforcement, military, and investigative experience.
Every case is documented and reported to a standard that holds up in court — because it has to.
This list is not exhaustive — it reflects most of the core investigation types Tharsis handles regularly. Casework can involve matters outside these categories as well; contact us to discuss your specific situation.
Rates vary by service and case complexity. Contact us for a fee schedule and consultation.
Kevin spent his career on the front lines of law enforcement and the military before founding Tharsis Investigations — closing his career as a Sergeant with the Pima County Sheriff's Department after years in patrol and investigations, and serving in the United States Marine Corps as a Reconnaissance Marine and Scout Sniper.
That background is the foundation of every case Tharsis Investigations takes on: documentation discipline learned from real courtroom exposure, surveillance tradecraft built from actual fieldwork, and a clear understanding of exactly where the legal line sits — because crossing it was never an option in uniform, and it isn't one now.
Kevin is also the author of The Investigator's Field Manual, a training curriculum and resource library used by law enforcement, private investigators, and a wide range of other investigative roles — from corporate and OSINT investigators to insurance fraud and workers' comp investigators — with no certification required to use it.
Get In TouchA complete training curriculum and specialty resource library — the Core Manual, 18+ add-on modules, a 19-item template library, and a 2-day hands-on training program. Built primarily for law enforcement investigators and licensed private investigators, but just as suited to social media/OSINT investigators, corporate and internal investigators, insurance and workers' comp fraud investigators, and anyone investigating an issue of their own within the bounds of the law. No certification is required to use it — it's the same foundational methodology whether you're already certified or building toward it.
