[6] Initially he wanted to join the Royal Netherlands East Indies Army but was rejected for poor eyesight.

[11] In 1908, while on an educational leave to Europe,[8] Killinger procured a loan of DM 50,000 with Marlitt, a German banker, for his planned coup d'état.

[18] Killinger started to discuss his plans to overthrow the government and install a dictatorship with his fellow policemen.

[13] He would end corruption, assure better treatment for the immigrants, diversify the economy, and strengthen the police force.

[22] Police officer Jatan was tasked to recruit a militia of Indo-Surinamese lathi warriors[23] from sugar estate Mariënburg[10] where a 1902 strike had turned into a massacre.

[7] Former police officer Jacob Schoonhoven was asked to form a posse of strong and tough men,[21] however he had second thoughts, discussed the matter with his priest, and reported Killinger to the Prosecutor General.

[4] During the trial, Killinger affirmed that he considered it his duty to correct injustices in Suriname even it meant breaking the law.

[26] Captain Hirschmann, in charge of security of Fort Zeelandia, considered the plan impossible, because 40 armed soldiers were held in reserve who would have been alarmed by the noise.

[27] On 3 April 1911, the judge considered that even though the coup was unlikely to succeed, it would have endangered the lives of the guards of Fort Zeelandia.

[30][7] On 18 April, Governor Fock commuted Killinger's sentence to five-year imprisonment to be served in the Netherlands.

[31][32] Fock wrote in his report to the Minister of Colonies that there was no reason for concern, because he considered the plan a fantasy.

[3][38] On 20 January 1914, Algemeen Handelsblad published an interview with Killinger who expressed no regrets, and was convinced that his coup would have been a success, if he had not been betrayed.

Notions that there was animosity between the Germans, Czechs and Slovaks were brushed aside by Killinger who painted an image of a prosperous, peaceful and democratic republic.
