HAMMOND | A Goshen, Ind., man has pleaded guilty to a drug conspiracy charge alleging he acted as an armed enforcer at a Hammond meeting regarding a drug debt in February 2008.

But the man won't likely be cooperating with other federal investigations.

Saul Galvan, following others charged in a case centered around Dyer's Blas Robles Sr., pleaded guilty last week in Hammond federal court as part of an agreement with federal prosecutors. Galvan, of Goshen, faces a mandatory minimum 10-year prison sentence. Galvan's sentencing is set for June 11.

Unlike several defendants in the case, however, Galvan did not agree to cooperate with other federal investigations. It was Galvan's choice to withhold cooperation, said Galvan's attorney, Jeff Schlesinger. Schlesinger would not say why Galvan did not want to cooperate.

Galvan is a Mexican citizen who has been in the United States for five years, Schlesinger said. Galvan's immigration status is "probably not" legal, Schlesinger said. Schlesinger expects Galvan to face deportation hearings.

Blas Robles Sr. and his sons Blas Robles Jr. and Jose Robles, all of Dyer, and George Leber and Andres Zaragoza, both of Hammond, all have pleaded guilty to drug conspiracy charges. Blas Robles Sr. and others have agreed to cooperate with federal investigations, according to court records.

A federal agent's affidavit paints Blas Robles Sr. as the head of a drug dealing network that collapsed last year after an Indiana state trooper intercepted 17 kilograms of cocaine on an interstate in Porter County. The organization crumbled as Robles tried to raise $100,000 to repay the drug supplier, according to the affidavit.
