Kip Holden, the mayor-president of East Baton Rouge Parish, said authorities were still trying to get a handle on the situation, but added, "The count is three officers dead possibly."

The victims may include police officers and sheriff's deputies

"There is still an active scene. They are investigating," he said. "Right now we are trying to get our arms around everything."

The shooter is believed to be down as well, Holden said.
