Case 1: Your forensic document examiner was brilliant. We can now obtain what is rightfully ours – our inheritance. People can be so devious when it comes to matters of money. All along we believed that Dad’s signature was a forgery. The evidence that you were able to obtain with respect to Dad’s state of mind around the time he allegedly signed the will was also vital. (Names withheld)

Case 2: The letters that this woman was sending almost destroyed our marriage. The efforts on the part of your investigators are to be commended. The matching up of documentation that you managed to obtain from her proved beyond doubt who it was. I know you won’t tell me, but I still can’t imagine how you obtained these records. I guess that’s a trade secret. I can’t thank you enough. (Name withheld)

Case 3: I had no idea that DNA could be obtained from a document. Your advice that people up to no good generally sweat rang true. Although there were no finger prints on the documents that were good enough to present to the court, the DNA removed from the paper proved that it was my brother who had falsified my fathers signature. (Name withheld)

Case 4: Thank for from us both. We can now rest easy now that this woman’s accusations have been disproved. People can be so devious when it comes to money: All these years my husband has paid out child support believing that the boy was his. The DNA you gathered from the tissue he used to blow his nose contains the truth. Who could have known it would be this easy, I feel sorry for the boy as I suspect she knows who the father is but I doubt she will ever tell him. (Name withheld)
