Jose Reyes, 17, and a 16-year-old boy are accused of disfiguring the girl’s body, including carving an upside down crucifix on her stomach.
Reyes and the 16-year-old 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 southeast Houston on February 5, they hit her with an ashtray, a toilet tank lid and a window blind rod, strangled her and also stabbed her in the face with a screwdriver.
“What happened in that vacant apartment was sadistic. What will eventually happen in the… courtroom will be justice,” Harris County prosecutor John Jordan told reporters.
Reyes, who was arrested on Sunday, made a brief court appearance. He is being held in the Harris County Jail.
The 16-year-old boy is in being held in a juvenile detention facility.
Jordan said the younger boy had heard Reyes claim that he had sold his soul to the devil and the 16-year-old wanted to do the same.
“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.
Jordan said that at one point during the assault, Cervantes yelled out to them, “Why are you doing this to me?”
Authorities are still trying to determine if Cervantes died from strangulation, the blows she received to her head, or from internal injuries from the sexual assault, Jordan said.
According to police, Cervantes’ partly clothed body was discovered early Saturday when a resident of the apartment building noticed the door to the vacant unit was open.
Jordan said Reyes’ family went to authorities after the teenager made “some admissions” to them about what had happened.
“They did the right thing. Clearly they were offended by his conduct,” he said.
At Reyes’ home, “there were some signs of devil worship and things of that nature,” Jordan said.
