Police have made an arrest in last week's Minnesota school shooting spree. Louis Jourdain, a student a Red Lake High School, was arrested Monday as part of the investigation into the shootings that appears to be widening.

Originally, local law enforcement officials believed that 16-year-old Jeff Weise acted alone when he killed nine people before killing himself last week. However, the arrest of Jourdain indicates that this could have been a wider plot.

Jourdain is suspected of helping Weise plan the assault at the high school and may have planned to take part in the attack.

Chris Dunshee, the principal of the Red Lake High School told the New York Times, 'They're saying that maybe the group he had run with knew something.'

The elder Jourdain is the youngest tribal chairman at age 40. After the shootings, he told reporters at a press conference, 'This is a wake-up call to us all. We need to spend more time with one another and paying more attention to our young people and what they're doing and what they are saying.'

It is doubtful he thought his words would hit so close to home.
