“After two other investigators couldn’t crack the case, Joshua Mailey and his team helped me to prove this using technology and good old fashioned gumshoe work. His evidence was very compelling, his reports were clean, and his costs were extremely reasonable. I would definitely hire his team to help my clients again.”
