NAMPA -- Authorities have released the names of four teenage boys charged in the shooting death of 16-year-old Roberto Gomez of Nampa.

Eight people in all - four adults and four juveniles - were indicted in the case.

Canyon County spokesman Joe Decker said the teen suspects have been charged with auto-waiver crimes, meaning their cases were automatically transferred into adult court because of the serious nature of the charges. Their names and charges are listed below:

  • Juan Manuel Menchaca Olvera, 16, of Nampa is charged with 1st-degree murder and robbery.
  • Jose A. Menchaca , 17, of Nampa, is charged with accessory to 1st-degree murder, aid and abet robbery, and perjury.
  • Isaac Bernal, 16, of Nampa, is charged with accessory to 1st-degree murder, and aid and abet robbery.
  • Gabriel Hernadez Olivo, 16, of Caldwell is charged with aiding and abetting 1st-degree murder, aid and abet robbery, and intimidation of a witness.

In addition, 42-year-old Maribel Menchaca, 35-year-old Olivia Hernandez Santana, 28-year-old Elizabeth Esparza, and 39-year-old Jose Menchaca are also facing charges.

Information in the now-unsealed grand jury indictments reveals that Gomez was robbed by two of the suspects the day of his death Sept 25. According to court documents, Maribel Menchaca shoved the teenager and yanked a gold chain from his neck, and Juan Manuel Menchaca Olvera took money and a Highpoint handgun from him "by means of force or fear."

Although both Maribel Menchaca and Juan Manuel Menchaca Olvera are charged with Gomez' murder, the indictments indicate that it was 16-year-old Menchaca Olvera who pulled the trigger.

Gabriel Hernandez Olivo was with Menchaca Olvera when Gomez was shot, according to the indictment.

Despite being charged as adults, the teenage suspects are currently being held in the juvenile detention center. Each faces a possible life sentence if convicted of the charges.

The four underage suspects appeared in court Friday afternoon. Each was appointed a public defender. Menchaca Olvera's bond was set at $1 million, while the other suspects received lower bonds: $500,00 for Hernandez Olivo, $100,00 for Jose Menchaca and $25,000 for Isaac Bernal.

Menchaca Olvera is due back in court Dec . 20; the other three suspects are set for Jan. 2 arraignments.
