Case file Sheikhdoon Abdullahi Mohamud, reference D C zero two zero four. According to an FBI special agent’s sworn complaint affidavit, the FBI began a national-security criminal investigation of Mohamud in about December twenty twenty-four. The affidavit alleges a confidential source exchanged messages with him through social-media and encrypted-messaging applications. The Justice Department said the complaint alleges Mohamud discussed an intended mass-casualty shooting at the Mall of America, including killing thirty to sixty people, buying a firearm, recruiting others, and identifying twenty-four October twenty twenty-six as the planned date. These are unproven allegations. According to the affidavit, on six October twenty twenty-six, Mohamud received a Norinco A K forty-seven rifle, four thirty-round magazines, and about two hundred rounds of ammunition from an FBI undercover employee; the FBI said the rifle had been rendered inert. The Justice Department said agents arrested him after he paid about six hundred dollars cash. The Justice Department said Mohamud, eighteen, of Richfield, Minnesota, was charged by complaint with one count of knowingly receiving a firearm and ammunition in order to commit a federal crime of terrorism. The Associated Press reported his federal public defender declined comment. The file’s open questions include what will be decided at the scheduled detention hearing, whether prosecutors will seek an indictment, whether Mohamud has entered any formal response, and what prompted the initial investigation. This has been an automated reading of case file D C zero two zero four at developing case dot com. Every fact you heard names a public source.
