Perpetrators: (3) Ivo Müller:Ivo Müller  was another frequent participant in events and demonstrations by Czech far-right groups, despite having a name that is not Czech but German. Some years before the attack he had sponsored a demonstration of National Resistance in Bruntál. He had known Vaculík and Cojocaru since grammar school. Müller's former teacher testified that neither Müller nor Vaculík had any issues with Roma schoolmates, but on the contrary: they were friendly towards them. Müller cooperated with the investigation and pled guilty to throwing the Molotov cocktail. However, he claimed that he was told by Lukeš that the targeted house was not inhabited, and that it was merely a storehouse of stolen goods. In his final speech, Müller said: "I did not expect (the attack) to have such a catastrophic outcome. I want to apologize to the families of Sivák and Malýs. I regret that such a little child was injured". Müller's attorney Markéta Políšenská  claimed that racially motivated attempted multiple murder charges were unfounded. She submitted that her client's act should be judged either as "endangering the public" or as "causing bodily harm"
