Le voici:
After the anonymous call to the police, police, ambulances and firefighters arrived. But too late, the girl was dead. After some investigative investigations and police, we found that most likely the girl died sunk, because the clothes she wore and her hair were completely drenched. Even so, they still lack evidence to close the case. Unfortunately, after researching the clothes and the rope that hung Melissa, we found a dna of 3 men, as we also found drinks and playing cards on the floor of Jardim das Paivas right next to Flora Beach. Finally, how did Melissa die? Sank or hanging? We still have to find out! If anyone has evidence, or indices or witnesses of how Melissa died. Contact 112. Thank you for reading our newspaper and until forever.
