Instructor Erin Lai

Erin has ten years of law enforcement experience and has spent more than half of her career so far in the Special Investigations Unit where she gained extensive experience in surveillance, online investigations, and undercover operations.

She has participated in the successful investigation and apprehension of numerous violent criminals, including several out-of-state missions that involved undercover operations, physical surveillance, and arrests.

Erin has authored over one hundred warrants directly related to homicide investigations.

Recommendation: Aubony Burns- Attorney in Homicide Unit (MDOP)- "I have worked on multiple homicide cases with Detective Lai.  She has handled roles requiring extensive and complex warrant writing and high stakes plainclothes/undercover intelligence operations on murder suspects.  Her attention to detail is case-making, and her understanding of the legal implications of her actions makes my job easy."

Instructor Daniel Yagi

With eighteen (18) years of law enforcement experience, Daniel has conducted thousands of hours of physical surveillance around the country. He has authored hundreds of warrants regarding violent crime and has directly been involved in the case development and prosecutions of homicides, robbery crew investigations, kidnappings, and high-level narcotic cases. He is a full time Detective with one of the largest and busiest cities in the State of Washington.

For over two years, Daniel has been an acting Detective Sgt. in the investigations division where he is responsible for coordinating in progress call outs of high-profile cases that require detective investigations (homicides, kidnappings, etc).

Daniel is the founder of Cypher Operations Group, where the company’s mission is to equip officers, investigators and tactical personnel with the most up to date case development methods in cell record analysis, physical surveillance, apprehensions and more.

Recommendation: Gary Ernsdorff- Supervising Attorney Special Operations Unit- "I have worked many investigations with Detective Yagi and he is clearly one of the best. He consistently demonstrates advanced knowledge in how cases can be developed by combining physical surveillance, historic cell record analysis and technical search warrants together. A winning combination."
