(AP) — A shooter killed one person and critically wounded four others at a yoga studio in Florida’s capital before killing himself Friday, officials said.

During a media briefing Friday night, Tallahassee Police Chief Michael DeLeo said four people are in critical condition following the shooting, which took place in a small Tallahassee shopping center.

The suspect fatally shot himself, DeLeo said. Authorities have not identified the shooter or the victims.

DeLeo said police are asking for anyone who saw something unusual around the time of the shooting to contact police. He said the shooter acted alone.

“We’re all very saddened and shocked by the events that occurred, but it’s important that people understand that there is no immediate threat outside of what has already occurred this evening,” DeLeo said.

A major commuter intersection was blocked off and businesses in the plaza were on lockdown as police investigated.

City Commissioner Scott Maddox was on the scene. He said on Facebook, “In my public service career I have had to be on some bad scenes. This is the worst. Please pray.”
