FORT LAUDERDALE -

Authorities say a Fort Lauderdale police officer is hospitalized in critical but stable condition after a shooting in a restaurant parking lot that left one other man dead.

Broward Sheriff's Office spokeswoman Keyla Concepcion says the officer was off duty Thursday night when he came upon an altercation between a couple in the parking lot.

Concepcion said early Friday that sheriff's detectives are still investigating what led to an exchange of gunfire between the officer and the man.

Authorities have identified the officer as Mark Shotwell, who has served in law enforcement for nearly 30 years. The name of the man who died hasn't been released.

Fort Lauderdale Fire Rescue pronounced the man dead at the scene. The Fort Lauderdale Police Department requested the assistance of the sheriff's office in investigating the shooting.
