Singapore has executed a man accused of coordinating a cannabis delivery, despite pleas for clemency and protests that he was convicted on weak evidence. Tangaraju Suppiah was sentenced for abetting the trafficking of 2.2 pounds of cannabis even though he was not caught with the drugs. Prosecutors said traced phone numbers showed he coordinated the delivery, but Tangaraju maintained he was not the person who communicated with others connected to the case. Relatives and activists sent letters to Singapore’s president to plead for clemency, and his niece and nephew made a video appeal raising concerns. Critics say Singapore’s death penalty has mostly snared low-level mules and done little to stop drug trafficking.
