Five men and women face first-degree murder charges in a fatal shooting last month at a mobile home park on the south side, authorities said.

The defendants, ages 18 to 20, were arrested in the death of 49-year-old Richard Ulibarri, the Pima County Sheriff's Department said.

Deputies responded to a gunfire call July 18 around 3:30 a.m. at the complex at 4444 E. Benson Highway. Ulibarri was declared dead at the scene, a news release said.

A second victim was wounded but survived.

The news release did not say what precipitated the shooting. That's still under investigation, said Deputy Marissa Hernandez, a department spokeswoman.

The five defendants were identified as:

  • Gabriella Acosta, 20
  • Noah Arguellez, 18
  • Nea Jones, 20
  • Ariel Monarrez, 20
  • Robert Yslava-Varela, 20
