Macedo's role in the atrocities, along with that of his employer, Julio César Arana, has been widely documented, with multiple reports and investigations implicating him in forced labor, starvation, and brutal punishments.

These actions were part of broader company practices incentivized by commission-based payments, leading to widespread human rights abuses under Macedo's management.

However, despite being briefly arrested, Macedo evaded significant legal consequences, partly due to political influence and corruption within Peru, and his later whereabouts remain uncertain.

Julio César Arana and his rubber firm employed Victor Macedo as an administrator at La Chorrera, Colombia, during the Putumayo genocide.

[7][a] During Macedo's management, the agency at La Corerra exploited indigenous groups, including Huitotos, Andoques, Ocaina, Yurias, Resígaro and Boras.

[20][21][22] Rómulo Paredes, a judge who investigated the Putumayo genocide in 1911, believed the first massacres in the region began under Larrañaga's leadership and continued under Macedo's administration.

[23][24] In the ninth chapter of his 1915 book El Proceso del Putumayo y sus secretos, Valcarcel examines the culpability of Macedo, Arana, Pablo Zumaeta and Juan B. Vega for the conditions in the region, the evidence collected by the 1911 commission that incriminates the senior managers with the atrocities, and Paredes's explanation for why they were not prosecuted.

Indigenous men, women, children and elderly people were compelled to work for Arana's firm, and were subjected to cruel punishment or death when they failed to meet the obligations imposed upon them.

Paredes wrote: "[h]unger has been perhaps the most terrible scourge which has fallen on the Putumayo" and that station chiefs did not allow natives enough time to cultivate food to sustain themselves.

'"[49][50][51][52] Saldaña Rocca, Casement, Hardenburg and Paredes had also collected information on several cases at La Chorrera where starvation was used as a means for capital punishment.

[53][54] The use of cepos, a device similar to a pillory, was reported at La Chorrera, Matanzas, Entre Rios, Atenas, Ultimo Retiro, Abisinia, Occidente, Santa Catalina and other stations that were under Macedo's administration.

Macedo was working with the Larrañaga family and Julio César Arana[h] as early as 1903 at an important settlement located below a waterfall named "Colonia Indiana", which was later known as La Chorrera.

[83][k] According to Hardenburg (1912): Another common form of punishment is that of mutilations, such as cutting off arms, legs, noses, ears, penises, hands, feet, and even heads.

Castrations are also a popular punishment for such crimes as trying to escape, for being lazy, or for being stupid, while frequently they employ these forms of mutilation merely to relieve the monotony of continual floggings and murders and to provide a sort of recreation.

[l][85]Macedo was first publicly implicated in the Putumayo genocide by Benjamin Saldaña Rocca on August 9, 1907, through a criminal petition filed against eighteen members of the J.C. Arana y Hermanos firm.

[91] Saldaña claimed that Macedo and his counterpart Loayza were responsible for the crimes of "swindling, robbery, incendiarism, poisoning and assassination" that was aggravated by "tortures by fire, water, the lash and mutilation" occurring under their management.

[41] On November 19, 1907, in an article published by Benjamin Saldaña Rocca, Reynaldo Torres said Macedo, Rafael Larranaga, and Jacob Barchillon had directed the 1903 massacre of Ocainas and this incident was denounced by Aristides Rodriguez.

[27] Among Hardenburg's deponents was firefighter Daniel Collantes, who in 1902 was employed on a river launch owned by Arana before Macedo ordered him to transfer to a rubber station.

Collantes stated at 4:00 a.m. the next morning, Macedo ordered eighteen employees from the section of La Sabana to flog the imprisoned natives to death.

Macedo signed a document of monetary gratification dated February 25, 1910, that was administered to members of the raid who Jiménez thought performed satisfactorily.

[147] A Barbadian named Norman Walcott told Casement in November 1909, he witnessed Victor Macedo flogging a native man of around eighteen years old.

In his deposition, Macedo gave testimony about several killings by Colombians in the region before 1907, most notably Crisostomo Hernandez, and he also said an uprising in 1905 at Ultimo Retiro was instigated by Gregorio Calderón.

[169][92] In his statement, Isaac Escurra said he saw eleven adult natives – ten men and one woman who had a child – who were imprisoned in the cepo next to Macedo's room.

Macedo gave an order to have lime poured over the eleven natives after an employee complained they were starting to smell bad due to their wounds rotting.

Macedo said the massacre was directed by Rafael Larranaga and was carried out as retribution for an uprising that occurred that year and resulted in the death of a Colombian rubber patron and his employees.

[192] Judge Paredes later showed several telegrams to Casement that were sent by "highly placed individuals in Lima" that requested the dismissal of Macedo's warrant.

[193] Several of these individuals include the deputies to Congress Hildebrando Fuentes and Ingoyen Canseco, and Emilio Rodriguez Larrain, the secretary to the President of Peru Augusto B.

[198][an] Paredes issued the warrant on the basis of a Peruvian law that stated: "[w]hen there is a corpus delicti, simple indications of guilt are sufficient to order the arrest of the accused".

[201] Valcárcel, who originally filed the arrest warrants against Macedo and Pablo Zumaeta, was dismissed from his office on October 31, 1911, by the Superior Court of Iquitos.

[207] Abelardo Aguero, Augusto Jiménez and Carlos Miranda, three of Macedo's station chiefs at La Chorrera, were also in Bolivia close to the border with Brazil, where they continued to exploit natives to extract rubber.
