He had a sad end. From Wikipedia:

Gilberto François “Betico” Croes (Papiamento pronunciation: [beˈtiko kɾus]; 25 January 1938 – 26 November 1986) was an Aruban political activist who was a proponent for Aruba’s separation from the Netherlands Antilles. This eventually occurred in 1986, but following a car accident on 31 December 1985 (the night of status aparte), Croes lapsed into a coma and never became conscious to see his accomplishment.
