DES MOINES, Iowa (AP) — Two teenage students were killed Monday and a man was seriously injured in what police said was a targeted shooting at an alternative educational program designed to keep at-risk youth away from trouble.

The injured man was identified as the program’s founder — a rapper who left a life of gangs and violence and has been dedicated to helping youth in Des Moines.

The partnership said the Starts Right Here movement “seeks to encourage and educate young people living in disadvantaged and oppressive circumstances using the arts, entertainment, music, hip hop and other programs.

Interim Superintendent Matt Smith said in a statement: “We are saddened to learn of another act of gun violence, especially one that impacts an organization that works closely with some of our students.

“I’ve seen first-hand how hard Will Keeps and his staff works to help at-risk kids through this alternative education program,” Reynolds said in a statement.

Nicole Krantz said her office near the school was put on lockdown immediately after the shooting, and she saw someone running from the building with police in pursuit on foot and in patrol cars.
