(SALT LAKE CITY)—A Utah investor facing charges for running a Ponzi scheme now is accused of trying to arrange the murder of those scheduled to testify at his trail. The 47-year-old Jeffrey Mowen of Lindon was indicted Wednesday for solicitation to commit a crime of violence, tampering with a witness and retaliating against a witness. Federal prosecutors say Mowen tried to get a fellow Davis County Jail inmate to kill four people in hopes of keeping them from testifying against him. Mowen is accused of running a scam that cost investors $10 million. Mowen could spend 20 years in prison if convicted of wire fraud charges.
