On November 6, Reuters disclosed Italian investigative documents: suspects had long been staking out Teacher Li's residence and rummaging through trash. One individual collected over 4,000 photos and 35 videos, while others offered 100 euros per day to hire people to track Teacher Li. Prosecutors suspect two main suspects acted on behalf of the Chinese police and maintained contact with personnel from the CCP United Front Work Department. The Milan prosecutor's office concluded its investigation into 10 suspects (8 Chinese citizens, 2 Italian citizens) on October 23; no convictions have been made yet.
