Wanderson was arrested on 25 February 2002, in Itu. According to the police, a 9 mm pistol found in Andinho's hideout matched that used on Toninho and on the kidnapping. The police claimed that three men from Andinho's gang, driving a silver Vectra, had attempted to stop a green Vectra shortly before Toninho's murder, intending to carry out a flash kidnapping. The green Vectra was hit by caliber 45 bullets and showed silver paint streaks from an attempt by the robbers to block its path, which also smashed one of the robbers' car headlights. This detail is confirmed by a security camera from the mall that recorded a car with one headlight off. While running away from that crime, the robbers ran into the Mayor's car, and either attempted to rob it too, or were irritated because Toninho was driving at the speed limit and blocking their way.
