SAN JUAN — A Puerto Rico police officer fatally shot two high-ranking officers and a policewoman on Monday after an argument at work that temporarily shut down the station in the US territory's second-largest city, authorities said.
The suspect was immediately arrested.
The suspect held a female lieutenant, a male commander, and a policewoman hostage in an office before he killed them, police spokeswoman Mayra Ayala said. Other police officials identified the officer as Guarionex Candelario.
Ayala said authorities were about to start negotiations with the suspect when the victims were killed. She said police did not have a motive.
Governor Alejandro Garcia Padilla said the suspect was injured during the shooting and remains hospitalized. Padilla declined to say what kind of injuries the officer received and how they were inflicted.
The shooting occurred inside the lieutenant's office at the police headquarters in the southern coastal city of Ponce.
Ayala said the suspect worked in the antidrug division. Officials said the victims were Lieutenant Luz Soto Segarra, Commander Frank Roman, and policewoman Rosario Hernandez. Roman was named Commander of the Year for Ponce in 2014.
