Investigators into the Boston Marathon attacks found female DNA on a bomb fragment, CNN reported on April 30. The DNA was found on a fragment of one of the pressure cookers used in the attack, but sources say that does not mean for certain that there was a female involved in a conspiracy with the Tsarnaev brothers.
Sources share that the DNA could have come from any female who had handled any of the items used to make the bombs detonated in the attacks. The FBI has taken samples from both Katherine Russell, Tamerlan Tsarnaev’s widow, and their 3-year-old daughter, to see if they are a match. Even if Russell’s DNA is a match, that does not mean she was involved in the bombings.
Russell’s attorney says she had no knowledge of the Boston Marathon bombings, and she is said to be cooperating with the investigation. A DNA expert told CNN that the DNA could also be from one of the bombing victims. News that female DNA was on the bomb is certainly catching people’s attention, but it is too early to know if it holds any relevance in the continuing investigation.
