ST. LOUIS (AP) — Charges could be filed Wednesday morning in the shooting at a downtown St. Louis business school.

Susan Ryan, spokeswoman for St. Louis Circuit Attorney Jennifer Joyce, says the office is reviewing a police report and will likely make an announcement on charges before noon.

A part-time student walked into an office at Stevens Institute of Business & Arts Tuesday and shot a longtime administrator in the chest, before turning the gun on himself. About 40 students in the building scrambled to safety. No one else was hurt.

The wounded men remain hospitalized Wednesday. A spokesman at Saint Louis University Hospital declined to discuss their conditions. Their names have not been released.

Police have not disclosed a motive but Police Chief Sam Dotson described it as a targeted shooting.
