 The courts reached the conclusion that the murders were not committed by a single person but by a group of at least four perpetrators, who became later known as "the picknick comarades", and were definitively convicted.
 The 1968 murder was found to be a case unrelated to the others, albeit that the gun, that probably originally belonged to small local criminality, might be the same involved in the actual Monster cases.
