Elisa Claps disappears in Potenza on September 12, 1993. He goes to the Holy Trinity to meet Danilo Restivivo, but he will never come out again. His body will only be found in 2010, Mummificate, with open jeans, the cut bra and personal objects next to it. The autopsy will speak of stab wounds and suffocation. The Ris will find the genetic traces of Restivivo on his shirts, sentenced to Italy at 30 years of age and in England to a penalty of 40 for the murder of one of his neighbor of his British house. But the mysteries remain: a bad game investigation, imaginative tracks, the attic perhaps never really controlled, the alleged silences of the parish, the sidetracks and omissions. Justice condemned the killer, but did not answer a question: who protected for 17 years the silence that Hidden Elisa has hidden on an altar? Is the complete analysis of the investigative journalist Alessandro Politi online, with all the details and anomalies of one of the darkest cases of our recent history.
