A woman in Argentina wants to marry the man who was convicted of murdering her twin sister.

Edith Casas, 22, believes that her fiance, Victor Cingolani, "would not hurt a fly" and is innocent in her sister's death, the BBC reported.

Cingolani is currently serving a 13-year sentence for the murder of Johana Casas, a model whose body was found in a field with two bullet wounds in 2010. Cingolani had dated Johana, but the two were not in a relationship
