The Appellant, a Nigerian national was intercepted at the Airport as she was checking in en route to Italy via Ethiopian Airlines. Her interception was in connection to suspicion of possession of narcotic drugs. Upon interception and checking the Appellant, she was found with 15 pellets in her bag which, upon examination turned out to be cocaine hydrochloride. Following her arrest, the Appellant was kept in observation and between 23/07/2012 and 26/07/2012 she excreted, through her stool, 48 pellets which also turned out to be cocaine hydrochloride. The Appellant’s defence was initially a denial of the charge. However, at the end the Appellant under oath in her own examination in chief admitted to have been found with the drugs. On the basis of the prosecution evidence and her own admission the Appellant was convicted and sentenced to life imprisonment hence this appeal. The appeal is against both conviction and sentence. In essence the Appellant’s complaint is that the conviction was faulty because firstly, that the chain of custody was uncertain
