Two Buffalo men have pleaded guilty to federal cocaine trafficking charges before U.S. Magistrate Judge Leslie G. Foschio, U.S. Attorney William J. Hochul Jr. announced Wednesday.

Christopher Carluccio, 38, and Vunnal Blair, 57, purchased cocaine from men in a car sales business on Broadway in Sloan and sold it to a network of customers in Buffalo, prosecutors said.

Carluccio and Blair were among 11 people arrested in June 2011, following an investigation into cocaine sales in Cheektowaga and on Buffalo’s East Side. To date, three have been convicted.

The pair face a maximum sentence of 20 years in prison and a $1 million fine.
