According to an article on Kaos en la Red, Martinelli's cousin, Guido Martinelli, is subject of the same investigation by Colombian security agency DAS that earlier implicated tourism minister Shamah in the sales of arms to Colombian armed groups (read: paramilitaries).
Guido Martinelli serves as Panama's ambassador to Italy - which we are sure is exclusively because of his excellent diplomatic qualifications.
The arms trafficking ring reportedly consisted of Salomo Shamah, Guido Martinelli and businessman Mario Guardia Durfee. The arms, bought in Central America and other countries, were stashed on land owned by Guardia Durfee in Bocas del Toro before being shipped to Colombia.
That land is the very same land where the indigenous Naso people used to live before the police moved in, destroyed their village and threw them off their land on behalf of a Canadian company building a hydroelectric dam and of aforementioned Mario Guardia Durfee, whose daytime job is that of one of west-Panama's largest cattle ranchers.
According to Almanaque Azul, he is also owner of a company called Unisys World Trade, which became notorious in 2003 for defrauding the National Lottery for $14 million, by selling products and services that were never delivered.
