HAVANA (AP) — More than a dozen islanders have been convicted in a case of poisonous black-market alcohol that killed 11 and sickened nearly 100, the Communist Party newspaper Granma reported Wednesday.

Two guards at the University of Havana’s Institute of Pharmacy and Foods were found guilty of stealing about 16 gallons (60 liters) of methyl alcohol and sentenced to 27 and 30 years in prison for theft, negligent homicide and causing grave injury.
