A law enforcement source with knowledge of the investigation says the juvenile son of tribal chairman Floyd Jourdain Junior has been arrested in the Red Lake shootings.
The source told The Associated Press that Red Lake High School student Louis Jourdain was arrested Sunday. The source said the younger Jourdain was arrested as part of an investigation into a potentially wider plot.
The Washington Post, citing two unidentified law enforcement officials familiar with the investigation, reports on its Web site that the younger Jourdain was suspected of helping 16-year-old Jeff Weise plan the assault and had expected to take part.
Nine people were killed in last week's attack by Weise, who then shot himself.
