Oribio pleaded guilty to the charges and was granted a specialized Drug Offender Sentencing Alternative (DOSA) program, which could reduce his sentence if he completes the treatment.

Why it matters

For the witness intimidation and firearm charges, Oribio received concurrent 18-month and 12-month terms, respectively.

  • The offenses occurred between late December 2024 and January 2025.
