Ongoing investigations into the crimes of the Uno Bianca criminal group, active between 1987 and 1994, are examining historical massacres and potential institutional involvement. 

In relation to the 1988 massacre in Castel Maggiore that killed Carabinieri Cataldo Stasi and Umberto Erriu, researchers are exploring theories that the officers were targeted for possessing sensitive information. Investigators are looking into the disappearance of approximately 30 percent of the Castel Maggiore Carabinieri Station's documentation from April 1988, as well as suspicious vehicle sightings and missing witness statements.

Concurrently, the Bologna Prosecutor's Office has interrogated former police officers Alberto Savi and Marino Occhipinti. This inquiry, initiated in 2023 following petitions from victims' families, seeks to identify masterminds or ‘covering agents’ who may have aided the gang. During questioning, prosecutors addressed the 1991 Pilastro massacre and previous claims made by Savi regarding the group's ability to influence public perception of the Carabinieri.

In September 2026, Savi and Occhipinti, both former officers convicted for the group's crimes, provided testimony to magistrates. The investigation aims to determine if there were additional accomplices or institutional sponsors behind the gang, which is linked to 23 deaths and over 100 injuries across Emilia-Romagna and Marche. New evidence has emerged in the form of a 1988 wedding agenda belonging to Occhipinti, which reportedly documents close personal ties between gang members, including Savi, Gugliotta, and Vallicelli. Investigators also revisited Savi’s 1995 claims regarding the gang receiving support from ‘cover agents.’
