Authorities say a man accused of participating in a multi-million-dollar scheme on Amazon threatened to kill himself in his Plymouth home Sunday night, reports the Star Tribune. It precipitated a standoff with police that ended peacefully several hours later, and 43-year-old Matthew Tieva was taken to a hospital for observation. He, Jessie Tieva and their company Sellers Playbook are the subject of a federal court complaint by the F-T-C and the Minnesota Attorney General’s Office.
