Killer and motives
The killer turn out to be food critic Marcus Crossman.
Upon admitting the murder, Marcus confessed that he and Louis went to college together. While they were in college, Louis would mock him of his job career, saying being a food critic only eats food that people made. When Marcus graduated college, Louis gave him a cupcake for their last day getting along with each other. When Marcus ate the cupcake, he passed out and woke up in the hospital. Questioning why he is in the hospital, the doctors told him that he was food poisoned. Marcus was furious when Louis tried to kill him. When he heard that Louis was competing in the contest, Marcus wanted to confront him at the docks about how Louis almost killed him with the cupcake. When confronting him, Louis still mocked him for being a food critic. Infuriated by him, Marcus slashed him with his own cleaver and sprinkled trail mix inside his body, to show him that the birds would eat food that people made. Judge Peterson sentenced him to life in prison.
