In just a few days you will be crammed into a house full of your family. Some you like, some you're okay with, and some you wish didn't even have to see once year - like that creepy uncle that gives everyone a Christmas card with a picture of him in a speedo.

Can you imagine what it will be like at this family's house as a woman plans to marry her sister's alleged killer?

Victor Cingolani is serving a 13 year sentence for the death of his model girlfriend Johana Casas in 2010. He is now engaged to her twin sister!

22-year-old fiancée Edith Casas was to wed her sister's convicted killer but held off on the ceremony due to media attention. Edith's mother is trying to prevent the wedding from happening altogether.

Marcelina Orellana, mother of Edith and Johana, said "We know this will be hard because she is an adult, but we will go to court to try to have her examined by a psychiatrist. As far as we are concerned, she does not know what she is doing."

Victor has apparently been able to warp Edith's mind because she plans on marrying him no matter what. Edith claims that Victor wouldn't hurt a fly and didn't kill her sister. Victor said in a TV interview recently "I loved Johana, but I love Edith, I have a beautiful bride and I am going to marry her."

It should be noted that there is also one other doing time for Johana's death.
