As President Obama prepares to address the nation this evening about the mass shooting in San Bernardino, California, investigators are still trying to get a clearer picture of what drove Syed Farook and his wife Tashfeen Malik , who allegedly carried out the rampage.
The rampage Wednesday, in which 14 people were killed and 21 others were injured, is now a federal terrorism investigation, with officials saying that Farook and Malik appear to have been inspired by ISIS, but FBI Director James Comey said there is no indication the two are part of an organized larger group, cell or network.
Still, federal authorities told ABC News they are investigating whether Farook may have left behind social media connections with one of the most active and significant ISIS recruiters, an American from Minneapolis now an FBI fugitive living overseas by the name of Mohamed Hasan who uses the on-line handle Miski.
