Boston bomb had woman DNA traces

Boston, April 30: A woman’s DNA has been found on at least one of the explosive devices used in the Boston bombings, adding a new dimension to the probe into the terror attack that killed three people and wounded over 200 others.

The findings, reported by the US media, have raised the possibility of involvement of a woman in the Boston Marathon twin blasts, which is blamed on two Chechenorigin brothers.

The US authorities have arrested Dzhokhar Tsarnaev, 19, on charges of using weapons of mass destruction, while his elder brother Tamerlan, 19, was shot dead by police.

“Investigators have found female DNA on at least one of the bombs used in the Boston Marathon attacks, though they haven’t determined whose DNA it is or whether its presence means a woman helped the two brothers suspected in the bombings,” The Wall Street Journal said quoting US officials.

“No one should expect that the investigation is over,” an investigator was quoted as saying by Fox News, according to which this raises the possibility of involvement of a woman.

Meanwhile, federal investigating authorities on Monday searched the Rhode Island home of parents of Katherine Russell, the widow of Tamerlan Tsarnaev, and the nearby family of a man identified as his mysterious mentor.
