Two teenage boys were hoping to make a deal with the devil when they sexually assaulted and killed a 15-year-old suburban Houston girl in a satanic ritual, a prosecutor said.
Seventeen-year-old Jose Reyes and a 16-year-old are accused of carving an upside-down crucifix on her stomach.
Reyes and the boy, whose name is not being released because he is a juvenile, each face a capital murder charge for the death of Corriann Cervantes.
Authorities say that after the boys lured Cervantes to a vacant apartment in southeastern Houston on February 5, they hit her with an ashtray and toilet tank lid and stabbed her in the face with a screwdriver.
Reyes, who was arrested on Sunday, made a brief court appearance on Tuesday. He is being held without bond.
Harris county prosecutor John Jordan said that at one point during the assault, Cervantes yelled out to them: "Why are you doing this to me?"
"The juvenile inquired ... that if he committed a murder, would that basically initiate him into being able to sell his soul to the devil, of which Mr Reyes said: 'Yes,"' Jordan said.
According to police, Cervantes' partly clothed body was discovered early on Saturday when a resident of the apartment building noticed the door to the vacant unit was open.
