KSTP --
... A criminal complaint released by the U.S. Attorneys Office names 36-year-old Jackie Rahm Little, also known as Joel Arthur Tueting, of Plymouth, as the arson suspect in both the fire last Sunday at Masjid Omar Islamic Center and Mondays fire at Masjid Al Rahma Mosque inside the Mercy Islamic Center.
... Minneapolis Police Chief Brian OHara said Sunday the department is adding enhanced patrols near places of worship and ensuring a swift response if someone calls 911 from a house of worship.
... Prior to the two arsons, the complaint states that Little was allegedly seen on surveillance footage going into the Minneapolis district office of U.S. Rep. Ilhan Omar. He then spray-painted 500 on the front door of the representatives office and took a photo of the graffiti. The complaint states that later in the same day, Little spray-painted 500 on the side of a patrol vehicle that was assigned to a Somali Minneapolis Police Department officer as well as inside the entryway of a market inside Somali Mall.
