Authorities have found an electronic version of the Al Qaeda magazine 'Inspire' at the home of a suspect in the Boston Marathon bombings, however it's unclear whether it was discovered on the technology belonging to Tamerlan Tsarnaev, Dzhokhar Tsarnaev, or Tamerlan's widow, Katherine Russell. Sources also revealed Friday evening that Russell communicated with her husband after the attacks and while investigators were trying to find him. All the while, Russell did not at any point contact investigators, it is believed.

Catherine Herridge reported on the communication, adding that one source says the back-and-forth between herself and the suspect included at least one phone call and possibly an email that included an attachment which was a photo of Tsarnaev released by the FBI.

The magazine 'Inspire' is widely known for its radical writings and past articles that included detailed instructions on how to make bombs and explosive devices.
