Epstein was DNA database mining. Body parts matching for clients perhaps? Apparently Epstein was also into DNA database mining.  That could be very useful for the global black market body parts and fluids industry if he were supplying it: "Epstein didn't spend much time on St. Thomas, according to locals, but his business is headquartered there in a commercial plaza that's also home to a Sami's Mini-Mart and the Happy Nails salon. There's no map to guide a visitor to the office and no signs on any door, though at least five Epstein entities are or have been registered in a suite there, according to public records. Among them are companies that hold his Gulfstream jets, Financial Trust Co. and Southern Trust Co., whose business is described as "DNA database and data mining" on a government website that lists Cecile deJongh as the office manager. DeJongh, the wife of a former governor of the territory, couldn't be reached for comment.” https://www.sfgate.com/news/article/The-mystery-surrounding-Jeffrey-Epstein-s-private-14090511.php
