Police in Puerto Rico are holding a wake for three officers killed by a fellow policeman at their station in the island's second largest city.

Caskets carrying the bodies of Lt. Luz Soto, Cmdr. Frank Roman and policewoman Rosario Hernandez were taken by a large motorcade on Thursday to the station where they worked in the southern coastal city of Ponce. Authorities said Guarionex Candelario is suspected of fatally shooting them on Monday in Soto's office following an argument.

Candelario was stripped of his weapon in 2005 after he underwent a psychological evaluation and was placed on administrative duty. The gun was returned to him in January 2015.

Soto was to be promoted to captain in February. Gov. Alejandro Garcia Padilla is expected to promote her posthumously.
