IT Media reported that his mother didn't throw away the models, but she put them in trash bags without his permission. He saw all the models disappeared from the room and jumped to the wrong conclusion. In the end, he burnt his collections by himself. Police estimated that he had collected almost all the models and the goods of Gundam available.
