Louisiana college student Caleb Wilson died after an alleged fraternity hazing ritual. Here's what we know.

A 20-year-old Southern University student died after an alleged off-campus fraternity hazing ritual in Baton Rouge, Louisiana, in late February.

The student, Caleb Wilson, "died as the direct result of a hazing incident where he was punched in the chest multiple times while pledging to Omega Psi Phi fraternity," Baton Rouge Police Department Chief Thomas Morse Jr. said at a news conference on March 7.

One person has been charged in Wilson's death so far and more arrests were expected, Morse said.
