Too soon to tell if a third person was involved

Sources have told The Wall Street Journal that a third person’s DNA has been found on some of the material used to make one of the bombs that exploded near the finish line of the Boston Marathon, killing three people and injuring more than 200.

So far, police have named only two suspects in the bombing: Tamerlan Tsarnaev, 26, who was killed during an altercation with police on April 18, and his younger brother, Dzhokhar Tsarnaev, 19, who was transferred to a federal prison in Fort Devens, Mass. last week.

While a third person’s DNA was found on some of the bomb material, sources told The Wall Street Journal that authorities don’t yet know who the DNA belonged to or whether a this means that a third person was involved. The DNA could have been from a store clerk who sold the materials used to make the bombs, or from a stray hair, authorities cautioned.

The news comes as FBI visited the home where Tamerlan Tsarnaev’s widow has been staying on Monday. Katherine Russell had been staying with her parents in Rhode Island since the bombing and The Washington Post reports that agents spent about 90 minutes inside the home. Russell’s lawyer has said that his client had no role in the bombings and that she is co-operating with authorities in their investigation.
