Somebody has been poisoned and the police round up 4 suspects. During interrogatioon, the 4 suspects made the following statements: Alu said "Gobi did it." Gobi said "Mutter did it." Khumb said "I did not do it." Mutter said "Gobi lied when he said I did it." If only 1 of the 4 is lying and only 1 is responsible 4 the crime, who is guilty?
