MINNESOTA ? The teenager charged in connection with last spring’s Red Lake, Minn., school shootings shows “significant promise for rehabilitation” and that’s a reason why his upcoming trial should remain closed to the public, a federal judge has ruled.

In an order issued Friday, U.S. District Judge Donovan Frank denied requests by the news media to have Louis Jourdain’s court files unsealed and his trial opened to the public. Because Jourdain is 17, the federal court system considers him a juvenile and his case is confidential.

Jourdain, son of Red Lake tribal chairman Floyd “Buck” Jourdain, is charged with conspiracy in connection with the March 21 shootings on the Red Lake Indian Reservation, which left 10 people dead and seven injured.

Jourdain’s cousin, 16-year-old Jeffrey Weise, carried out the shootings. Weise committed suicide as police converged on Red Lake High School. Authorities believe Weise and Jourdain – communicating through e-mails and text messages – plotted the attacks together over a period of months.
