It was the 19th of December, 2010, and it was finally the wedding day of 29-year-old Rogerio Damascena and 25-year-old Costa Coelho, from Recife, Brazil. The duo had been dating for three years and it was time to tie the knot. They had planned an extravagant wedding which was held in Camaragibe, Brazil. Over 200 guests attended the event and watched the seemingly happy couple exchange vows and dance the evening away into the early morning hours.
At around 2AM when the party was in full swing, Damascena departed the main hall, whispering to his new wife that he had a surprise for her. When he came back moments later, he kissed his Coelho before retrieving a .38 calibre pistol from his pocket and shooting her in the chest and head, killing her.
After shooting Coelho dead, he turned the gun on the guests. He targeted his best man, Marcelo Guimaraes, and shot him dead before turning the gun on himself and ending his own life. Many later speculated that Damascena, who had an extreme jealous streak, had suspected Coelho of cheating on him with Guimaraes.
