A source tells Fox News that investigators found a woman’s DNA on pieces of at least one of the Boston Marathon bombs. Experts say that doesn’t necessarily mean a woman helped build the devices. The source says investigators are looking at what kind of help the suspects may have had.

Rick Leventhal reported that the DNA was supposedly found on bomb components. Experts caution that a female could’ve unknowingly handled pieces of the bomb before it was assembled. According to The Wall Street Journal, the DNA prompted officials to visit the Rhode Island home where suspect Tamerlan Tsarnaev’s widow is staying.

The FBI confirmed that it went into the home where Katherine Russell is currently living with her parents. Agents spent 90 minutes in the home and left with what appeared to be a computer and a zip-locked bag with personal items. They drove off in a caravan with Russell and her attorney. She has since returned to the home.

The cause of death has been determined for Tsarnaev, but that information won't be released until a next of kin claims his body.
