A student went on a shooting spree injuring four students before he was shot by police. SuccessTech is an inner city school in Cleveland, OH:

A 14-year-old gunman shot students and teachers at a Cleveland high school, wounding four, and was then killed, the mayor told CNN affiliates WOIO and WKYC.

Witnesses told WKYC that the 14-year-old gunman was upset about being suspended for fighting earlier this week. He came to the school Wednesday with a gun in each hand and began firing.

Students said they took cover in closets after the school principal announced a “Code Blue” on the intercom.

The gunman was described by fellow students as “odd.”

SuccessTech is a nontraditional high school, according to local school officials.

Here’s a snippet about the school from their website :

Your journey can begin here! SuccessTech Academy is a small, nontraditional high school that provides a learning environment in which all students believe in their ability to succeed. Students will achieve their goals as they progress through our problem-based, technology infused curriculum. Each student will develop a personalized learning plan with his or her teacher and parent. Students will be required to participate in service learning, which enhances what is taught in school by extending learning beyond the classroom into the community. The SuccessTech Academy learning community will have high standards and a rigorous curriculum that promotes cooperative learning, inquiry -based problem solving and communication skills.

It looks like they were trying to create a different kind of learning environment.
Update: It turns out that the boy shot himself.
