Two sheriff’s deputies who stopped a gunman Friday morning at Naval Air Station Pensacola were injured in the shooting that killed four people and injured several others.

Authorities said the suspect was among the four people killed. Seven others, including the two deputies, were injured and taken to the hospital.

The shooting happened just two days after a U.S. Navy sailor shot three people and killed himself at Pearl Harbor.
