For the first time in the US, an identical twin has been convicted of a crime based on DNA analysis.
On 21 August, a jury found Russell Marubbio, 54, guilty of a sexual assault that occurred in Woodbridge, Virginia, in 1987.
Virginia-based Parabon NanoLabs ran an analysis on the DNA sample found at the scene nearly four decades ago. Genealogist CeCe Moore then traced the perpetrator’s family tree and seemed to hit a wall when the sample led to identical twins.
Usually, that would be the end of using DNA to solve the case. Identical twins have the same DNA – almost. There are sometimes a few cells that split and evolve differently.
