Brown University President Christina Paxson says the school's vice president for public safety and emergency management is on leave.

That's while the school works on an after-action review of the shooting.

In the meantime, she hired a former Providence police chief to step in.

The leadership change comes as the U.S.

Department of Education said that it would investigate Brown in response to the shooting.

A statement from the agency cited concerns about security at the school and the university's emergency notification system.

Paxton also told the university community that a team is working on upgrades to campus security.

The plan is to have them in place before the start of the spring semester.
