Mark Epstein is Jeffrey Epstein's younger brother and is available for a DNA test. The Border Patrol has DNA tests which can tell if an illegal immigrant adult is related to the children with him or her in a matter of minutes or hours. Unfortunately I cannot find details about the tests, test kits, or cost to DHS. But the test(s) cannot be that expensive if the intent is to prove or disprove a family link.  Many patriots would gladly pay for the DNA test. I would be first in line with a fistful of money.
