Officials are still investigating the massacre but believe Farook and Malik were radicalized at some point, with co-workers describing how Farook began growing out his beard and friends describing how he essentially vanished from their lives.
There’s a prominent theory that’s still not officially confirmed that has Malik radicalizing Farook. Malik pledged allegiance to the leader of terror group ISIS in a Facebook post just before carrying out the attack.
Meanwhile, Farook’s family has come under suspicion, including Farook’s dad, who is also named Syed Farook, being placed on a terrorism watchlist. The family claims they knew nothing about the attack.
