Last week’s deadly attack on Israeli tourists in Bulgaria has led to an international search for the bomber’s identity, but now, according to a Bulgarian television report, the identity of a possible female accomplice is being sought after as well.

A report from BTV television stated that “biological evidence” was found in a hotel room used by the suicide bomber who killed 5 Israelis, a local bus driver, and himself, showing him with a woman in Varna, Bulgaria, one day before the attack.

Bulgarian authorities are looking for the woman and suspect she may have helped execute last week’s terrorist attack by helping to guide the bomber around Bulgaria.

According to a cab driver believed to have driven the terrorist near the scene of Wednesday’s attack, the man who blew himself up “spoke Russian well”.
