Unsolved/ unresolved crimes

Has anyone really dissected these unresolved crimes that have just been forgotten and can someone analyze and give the current status: 1. Shakahola - like what happened there, are investigations and exhumations still ongoing?? How many bodies?? Who murdered them?? 2. Rita Waeni- her dismembered body was found beginning of the year and a decoy foreigner was arrested but the case remains lost in the void 3. Bodies in Quarry: several bodies in plastic bags were found in Mukuru, a fake serial killer arrested and he later escaped 4. The Endarasha fire and the missing kids 5. Bodies found in river Yala and various dams

And many more strange cases. They only stay in the news cycle for 3 weeks then we move on with no conclusions and PR arrests. I can imagine how many strange deaths have gone unreported and how many potential murderers we have around. Stuff is scary af
