Marcelino Rodriguez, of Eddy, Texas, will spend three to five years in prison and his brother, Miguel, from Corpus Christi, Texas, has been sentenced to four to eight years.
State prosecutors say Marcelino Rodriguez was arrested on unrelated drug charges in Crawford County in August 2010, and continued to direct the operation using phone calls from the county prison. Those calls were recorded by law enforcement, which helped lead to the charges.
The brothers are 29 years old.
Their sister, 30-year-old Laura Rodriguez, of Chilton, Texas, was sentenced to six to 24 months in jail for conspiracy for her lesser role.
