Mario Oscar Ferreyra, better known as Malevo Ferreyra (June 17, 1945 – November 21, 2008) was an Argentine police chief. Being a police officer during the last Argentine Dictatorship, he participated in the State terrorism, repressing left-wing guerrilla groups in Tucuman province. After the return of democracy, he would become the chief of Tucumán Provincial Police. In this position, Ferreyra became involved in the murder of guerrillas members, and innocent civilians suspected of the same. He would later be prosecuted and discharged from the force. He shot himself in 2008, when facing his imminent arrest, and his suicide was broadcast live on national TV. Early life Mario Oscar Ferreyra was born on June 17, 1945, in Los Pereyra, Cruz Alta, a locality east of San Miguel de Tucumán. When he was 18 years old, he enlisted in the police. He had been deemed physically unfit because of his small stature and low weight, but managed to enter the force thanks to a relative. In 1973, he fought against 15 demonstrators of the Juventud Peronista during a brawl downtown, in which he was hit with a glass bottle, leaving him a scar that would last for the rest of his life. Two years after this, he killed Julio Alsogaray, a militant of Montoneros guerrilla faction, in a one-on-one confrontation. He shot him with a FN FAL rifle. During the Military Junta rule, he was suspended for two years and five months, after being accused by his superiors of the senseless use of lethal force. In 1986, after the return of democracy, he was prosecuted for the killing of the well known criminal Enrique "Prode" Correa, but justice acquitted him for lack of evidence. One year later, when he was the chief of Robos y Hurtos, (Robbery Division of the Police,) he was involved in a shooting in the northern approaches to the city of San Miguel de Tucumán, in which two members of a prominent crime family were killed. In 1988, he was accused of the killing of another member of that same crime family, Daniel Carrizo, who had also been tortured in a cell of the Robbery Division's headquarters before his death. He was again acquitted. In January 1990, he was named chief of the General Investigations Division, and two months later led a police strike against governor José Domato, which forced the Gendarmería Nacional Argentina to take the law
