Federal court records show Alanis is facing one count of conspiracy to possess with intent to distribute cocaine, and two counts of possession with intent to distribute.

Alanis is one of eight defendants in a drug trafficking investigation that also netted the arrest of his brother — Progreso Assistant City Manager Francisco Javier Alanis. 

Francisco was arrested in October 2023 and accused of being involved in a drug trafficking scheme from January 2020 to March 2022.
