If you are looking for a loss prevention investigator, Tristar Investigation has decades of experience in the field. We have seen it all before, from isolated single employee “crimes of opportunity” to sophisticated theft rings. We cover all of California, so whether you need a loss prevention investigator in Los Angeles County or Orange County, or throughout the state, we are ready to serve your loss prevention investigation needs.
There are a number of tactics we can employ in loss prevention investigations including covert surveillance, undercover investigators, polygraph tests and employee interviews. In some cases we have uncovered conspiracies that involved numerous employees that documented collusion by several employees involved in a theft ring.
