The parents of a five-year-old girl who disappeared from a home in central Argentina have slammed police for losing a security camera video that may have been crucial in finding out who kidnapped their child. Guadalupe Lucero was last seen at a birthday party at her aunt's home in the city of San Luis on June 14 around 8pm. She reportedly disappeared after stepping outside the home's entrance to play hopscotch with a group of children. Authorities gained access to a video that appeared to show Lucero being led away by a woman, but inexplicably lost the footage. Investigators were unable to verify if the girl in the footage is indeed Guadalupe. Guadalupe is 3'6' and has a birthmark above the left side of her jaw near her ear. She also has a chipped front tooth. According to Argentine news channel Todo Noticias, Interpol was reviewing a text message that Yamila Cialone received last Tuesday at 2.14am from Puebla, Mexico. The network was able to obtain a copy of the screen grab that showed the sender asking the distraught mother: 'Do you want Guadalupe back alive?' At 2.15am, the sender asked Cialone if she was the mother and then waited an additional minute to ask if she wanted her daughter back.
