There are some things you just don't do: Like marrying the man convicted of killing your twin sister, for one. Argentinian Edith Casas did just that recently, wedding the alleged killer of her twin sister in a ceremony that drew more than just simple objections from a crowd outside the event, The Daily Mail reported.

At a ceremony in Pico Truncade in southern Argentina, Edith Casas married Victor Cingolani roughly one year into his 13-year sentence for the 2010 murder of her twin sister Johana Casas. Cingolani was released just for the marriage ceremony, and returned to incarceration shortly after the couple wed.

Edith's family has virtually disowned her after they learned of her decision to marry Cingolani. Her mother thinks she may be suffering from "psychological issues" and tried to stop the wedding from happening. 

"I've always said that she is threatened by the Cingolani family; I'm afraid that something might happen to her because he is a killer and a manipulator," the mother of the twins, Marcelina del Carmen Orellana, said to the media, according to Fox News.

Johana was discovered dead in the same city where her sister married her alleged murderer, shot twice in the head just days before her 20th birthday. The majority of Edith's family and neighbors denounced the union as a "terrible betrayal," with a mob amassing outside the civil registry office where the pair were married, showing up to pelt the couple with eggs and rocks, according to Fox News. 

Cingolani has always argued the verdict was a mistake. He says he's serving time for someone else's crime, and is currently appealing the charges against him. 

"All the evidence points to another person," he has claimed, according to Fox News.

"I'm getting married because I love Edith. I didn't think the wedding would have so many repercussions worldwide," he said to local news network, according to the Daily Mail.

Edith proclaims her husband is innocent of killing her sister.

"I'm going to get married to the person I love and not the person who killed my sister," she said last year, The Daily Mail reported.

"Victor is not a violent person and I'm not mad. We've got no doubts about what we're doing. We love each other," she argued at the time.

Edith's father disagrees with that assessment. "Johana is with God and Edith is with the Devil," he told Clarín newspaper in December, according to Fox News.
