The Everglades National Park reported an active shooter at the park who shot at park rangers “unprovoked.” The tweet identifies the suspect as a 33-year-old white man.

The national park called on visitors and residents in Flamingo, Fla., to shelter in place, noting the main park road was closed “for public safety.”
