The Texas Alcoholic Beverage Commission is moving forward with two investigations.
The agency is looking into who supplied alcohol at two underage parties.
Agents confirm several arrests are likely to stem from a party that was busted Saturday night, near Iola.
Officers believe 50 people were there, along with four kegs and liquor.
13 have already been arrested for underage drinking.
TABC agents also expect an arrest in connection with a party that took place the week before, in Bryan.
Police say teens Gus and Dillon Benavides and Alex Dicky attended that gathering before they were killed in an early morning wreck.
