By the time the reporters from the major outlets arrived, the material they could search for was very limited. The only thing they could do was mention what the police said and cover that. Furthermore, they could mostly only provide simple descriptions of the situation. As for the reasons for the situation, they stopped themselves from randomly speculating without any solid proof.
This resulted in the mass media drawing a lot of attention to the matter, but they did so without quickly coming to any conclusions as they searched for evidence. So then a lot of viewers had their curiosity piqued, but with no results, their desire for gossip resulted in many of them seeking answers from alternative sources.
