A Cuban immigrant who pleaded guilty to having a role in the theft of more than $50 million of pharmaceuticals from an Eli Lilly and Co warehouse in northern Connecticut was sentenced on Wednesday to 6-1/4 years in prison. Yosmany Nunez, 42, of Southwest Ranches, Florida, is the first defendant to be sentenced among five who pleaded guilty over the March 13, 2010 heist in Enfield, Connecticut, which borders Massachusetts, federal prosecutors said.
