“After local and federal law enforcement refused to investigate the theft of my great aunt’s estate worth almost a million dollars, CSI tackled the case, solved the crime and found justice for my family.  Chip Devasher presented the case to the FBI and the suspect was later indicted, found guilty and served several years in federal prison.”

Jim McKenzie, Lexington, KY

“My former employee embezzled hundreds of thousands of dollars from my company.  I found out after it was too late and contacted CSI for help. They investigated and found my employee red handed. Chip Devasher handed over his investigation to the Lexington, KY Police and an arrest was made.  Justice was served and my former employee was sentenced to 8 years in prison.”

Ed Thurmond, Lexington, KY

“My daughter walked away from rehab and disappeared into the mountains of Eastern Kentucky.  I was desperate to find my daughter and get her the help she desperately needed. Chip Devasher used his law enforcement contacts, developed informants and found her before it was too late.  Thanks to CSI, my daughter is now getting the help she needs.”
