Clunis was one of four cops who were shot during a police operation in Horizon Park, Spanish Town, St Catherine on June 12.
Constable Decardo Hylton and Corporal Dane Biggs who were among the wounded cops died the same day.
Meanwhile, as news of Clunis' passing spread, several police officers descended on the Kingston Public Hospital in shock.
Superintendent Steve Brown was among them.
Brown said he spoke to Clunis twice today and was to have met him this afternoon, but was delayed by the rain.
