Vecto ordered a knight (miles) Lazario to conduct an investigation. On the 5th of December Lazario supervised the testimony of nine witnesses and had their testimony recorded. Some of them reported that Mengus was a robber and had a bad reputation. Others claimed that they thought that Mengho was good or that they did not know him. Several testified that Mengho was suspected of the crime.
