Documents filed in Skagit Court say Arcan Cetin, who was charged Monday with five counts of first-degree murder. told detectives who interviewed him that "he did bring the rifle into Macy's and shot all 5 victims."

The 20-year-old man suspected of killing five people at a Macy's makeup counter had a string of run-ins with the law and was described by a neighbour as "creepy, rude and obnoxious".
