NAMPA -- Eight people have been arrested in connection to the September shooting death of a teenage boy in Nampa.

Roberto Angel Gomez, 16, was gunned down in the street near his home at Powell Avenue and 11th Avenue North the night of Sept. 25. He was rushed to a local hospital, but died from his wounds.

The investigation into the slaying stretched on for months.

“These arrests are the result of many hours spent by detectives investigating this case," Nampa Police Eric Skoglund said. "A grand jury reviewed evidence presented to them, related to these two cases, which led to multiple indictments.”

Nampa Police announced the arrests of four adults and four teens on Dec. 6, all but one of which is charged in Gomez' murder.

Canyon County spokesman Joe Decker said the juvenile suspects have been charged with auto-waiver crimes, meaning their cases will be automatically transferred into adult court because of the serious nature of the charges.

The suspects and charges are listed below.

  • Maribel Menchaca, 42, of Nampa – 1st degree murder and robbery
  • Elizabeth Esparza, 28, of Caldwell - Accessory to 1st degree murder, aid and abet robbery, and perjury
  • Olivia Hernandez Santana, 35, of Caldwell – Accessory to 1st degree murder, intimidation of a witness and perjury
  • A 16-year-old Nampa boy – 1st degree murder and robbery
  • A 17-year-old Nampa boy – accessory to 1st degree murder, aid and abet robbery, and perjury
  • A 16-year-old Nampa boy – accessory to 1st degree murder, and aid and abet Robbery
  • A 16-year-old Caldwell boy – aid and abet 1st degree murder, aid and abet robbery, and intimidation of a witness
  • Jose Menchaca, 39, of Nampa – aid and abet robbery.

Police have not released a motive in the shooting. Skoglund said investigators believe only one person fired the shots that killed Gomez, but declined to say which of the suspects is believed to have pulled the trigger.
