Three men who spent more than 20 years in prison for murder were freed in a historic ruling after new tests found none of their DNA on evidence in a case that captivated the U.S. territory.

Nelson Ortiz, Jose Caro and Nelson Ruiz hugged loved ones tightly after prosecutors requested that charges be dropped due to a lack of evidence. The men had repeatedly sought a new trial after they were convicted in 1995 in the killing of 21-year-old pharmacy student Glorimar Perez.
