Adan, who hailed from a Somali family that had settled in the United States, grew increasingly interested in Islam and withdrew socially before he stabbed 10 people in St. Cloud, Minnesota, the FBI said. FBI special agent Rich Thornton said: "One could reasonably conclude his actions were consistent with the philosophies of violent radical Islamic groups.” Mr Thornton said the FBI is still investigating Adan's activities and wants access to his cell phone. He said: "Dahir Adan's iPhone is locked and we are in the process of assessing our legal and technical options to gain access to this device and the data it may contain.”
