Who Killed Theresa?

"It was a Tuesday, a beautiful day. Mario's parents gave him a small motocylette as a present.  Mario spent many hours enjoying it, giving rides to his family and friends. The last ride was reserved for a petite ami, Diane Dery. The families would never see them alive again.The next day, Wednesday, May 21st 1975, the bodies were discovered in a field near the Saint Hubert airport. Mario had been beaten, then shot six times with a .22 caliber gun. Diane had been shot once in the back of the head with the same caliber gun, and once in the chest. She may have been raped, and her body was placed on top of Mario's. The bodies were placed in such a way as to suggest they had a sexual relationship."For more information please visit the website: http://theresaallore.com/2018/05/diane-dery-and-mario-corbeil-may-20-1975-wkt2-17/
