The discovery resulted from the documentation process for the book Can Fontanelles. La història d'un país a través de la seva gent. This work reconstructs the history of a Piera farmhouse using family archives, providing key details about Guilera's fate.
Following the data provided to democratic memory agencies, the Generalitat de Catalunya confirmed he is buried at the Caputxins Cemetery in Mataró. The site was recently honored on March 7 with commemorative plaques for those in mass graves.
The identification was supported by historians Maria Salicrú-Maltas and Juli Cuéllar, who have named over 250 individuals buried there, mostly soldiers who died in local military hospitals during the war.
