Police said the man who committed the crime with him, Diego Hernandez-Rivera, was also charged with murder.

Investigators believe they shot and killed 15-year-old Genesis Cornejo-Alvarado back in February.

Cornejo was missing for a month.

Cornejo was reported missing by her family. Jersey Village police officers searched apartment complexes in west Houston looking for her but believed she was "actively hiding from them," according to Foerster.

Conejo's body was found on the side of the road on Sharpcrest near Corporate. Police said she had been shot twice at close range. She was positively ID'd two weeks later.

The Harris County Institute of Forensic Sciences released a photograph of three rings she was wearing and a clothing description that included white high-top Converse tennis shoes. Cornejo was also wearing white high-top Converse tennis shoes when she went missing.

Alvarez-Flores, 22, and Hernandez-Rivera, 18, are charged with her murder. During their first court appearance, they smiled and waved at the cameras.

According to court records, a 14-year-old girl says she was kidnapped by the two, held against her will in an apartment on South Gessner near Westheimer and sexually assaulted. She told police Alvarez-Flores, nicknamed "Diabolical," was the leader. Her captors were MS-13 gang members and that they worshipped Satan. The teen also told investigators they called Satan the "Beast," and another girl named Genesis was also at the apartment. When Genesis criticized a shrine dedicated to their satanic beliefs, she said, Genesis disappeared.

The 14-year-old was able to lead police to Alvarez-Flores and Hernandez-Rivera. A prosecutor says Hernandez-Rivera admitted to shooting Genesis.
