I hired Linked Investigations on several occasions in the past with successful results.  Information that I felt were impossible to recover proved to be very possible!!  I had custody issues a long time ago which was why I initially hired Linked.  They certainly helped my claims in court.  I recently hired Linked for my business and once again, was successful collecting the information I needed.  Obviously very confidential, VERY experienced, intelligent and has excellent referrals for attorneys, etc.  I would HIGHLY recommend Linked Investigations to anyone.  There are other investigative companies, but I did my interviews and research.  Linked is the best.
