Outraged OAS members voted unanimously to sever diplomatic relations with his government and impose economic sanctions on the Dominican Republic. The brutal murder on Friday, 25 November 1960, of the three Mirabal sisters, Patria, María Teresa and Minerva, who opposed Trujillo's dictatorship, further increased discontent with his repressive rule. Trujillo's "central arch" was his instinct for power. This was coupled with an intense desire for money, which he recognized as a source of and support for power. Up at four in the morning, he exercised, studied the newspaper, read many reports, and completed papers before breakfast. At the office by nine, he continued his work, and took lunch by noon. After a walk, he continued to work until 7:30 pm. After dinner, he attended functions, held discussions, or was driven around incognito in the city "observing and remembering." Until Santo Domingo's National Palace was built in 1947, he worked out of the Casas Reales, the colonial-era Viceregal center of administration. Today the building is a museum; on display are his desk and chair, along with a massive collection of arms and armor that he bought. He was methodical, punctual, secretive, and guarded; he had no true friends, only associates and acquaintances. For his associates, his actions towards them were unpredictable. Trujillo and his family amassed enormous wealth. He acquired cattle lands on a grand scale, and went into meat and milk production, operations that soon evolved into monopolies. Salt, sugar, tobacco, lumber, and the lottery were other industries that he or his family members dominated. Family members also received positions within the government and the army, including one of Trujillo's sons who was made a colonel in the Dominican Army when he was only four years old. Two of Trujillo's brothers, Héctor and José Arismendy, also held positions in his government. José Arismendy Trujillo oversaw the creation of the main radio station, "La Voz Dominicana", and later the television station, the fourth in the Caribbean. By 1937 Trujillo's annual income was about $1.5 million ($ million in ); at the time of his death the state took over 111 Trujillo-owned companies. His love of fine and ostentatious clothing was displayed in elaborate uniforms and suits, of which he collected almost two thousand. Fond of neckties, he amassed a collection of over ten thousand.
