According to The Weekly Standard, authorities are still investigating how much Tamerlan Tsarnaev's wife knew about the Boston bombings. The report states that law enforcement officials now believe 24-year-old Katherine Russell Tsarnaeva called Tamerlan to let him know the FBI was looking for him after she saw his photos on the news. Though officials believe Tsarnaev was already aware, he and his younger brother went on the run a short time later, culminating in his death and Dzhokhar Tsarnaev's arrest. Investigators were told of the alleged phone call by Dzhokhar in his interrogation before he was read his Miranda rights.
