HOUSTON (KTRK) -- A 22-year-old man is facing a felony charge after he allegedly had sex with 12-year-old twin sisters he met online.
William Alexander Alvarado is charged with continuous sexual abuse of a child.
According to his charging documents, Alvarado came into contact with the victims in August 2015 after he sent one of them a Facebook friend request.
A month later, according to the document, Alvarado went to the girls' home and sneaked into their bedroom via a window. One of the sisters looked on as Alvarado touched her twin inappropriately.
The next day, he allegedly picked up the same sister and took her back to his home. Alvarado had the girl climb through a window into his bedroom because he still lived with his parents. It was there he allegedly sexually assaulted her.
The same girl said Alvarado took her to a motel a couple months later and again the two had sex, according to the charging document.
One day, Alvarado went to the girls' home and took the twin sister back to his house, where he sexually assaulted her, according to the charging document.
Investigators say when they questioned Alvarado in May, he admitted to having sex with one sister four times and the other once.
Alvarado's bail has been set at $100,000. He has not yet been arrested.
