DFS recommends the use of the Missing Person Family Reference Collection Kits. These kits can be obtained at any of the Regional Laboratories or Medical Examiner’s offices. Follow the instructions provided with the kits, and submit along with a completed Request for Laboratory Examination (RFLE). If you do not have the Missing Person Family Reference Collection Kits, download and complete this document for each reference sample being collected, and submit along with the reference samples/alternate known and a completed RFLE.
