"My husband was accused of several horrible crimes by my daughter. I was confused and didn't know what to think.. We hired Mr. Coates and he ultimately got to the bottom of our nightmare. My husband was exonerated and my daughter was exposed as a liar. My husband passed away shortly after the case was resolved. If it weren't for Mr. Coates, my husband would have died in prison an innocent man.

“Thank you Mr. Coates and God bless you!"
