Austro-Hungarian authorities arrested and prosecuted the Sarajevo assassins (except for Mehmedbašić who had escaped to Montenegro and was released from police custody there to Serbia) together with the agents and peasants who had assisted them on their way. The majority of the defendants were charged with conspiracy to commit high treason involving official circles in the Kingdom of Serbia. Conspiracy to commit high treason carried a maximum sentence of death which conspiracy to commit simple murder did not. The trial was held from 12 to 23 October with the verdict and sentences announced on 28 October 1914.
