A man brings a dead body over his shoulder for a long distance and throw it in a wet cement of a construction site. However, the body does not sink and on the next morning, the man is found trapped, buried to his waist in the cement. Catherine investigates the crime scene and find it hilarious. David Phillips finds that the woman was stabbed once in her chest and the man refuses to give his name. Meanwhile, Warrick and Nick investigate the call of a gas company, who found the body of Alyona Ivanovna in her apartment. The company was called by the residents that smelled a gas leak in her apartment and her head inside the oven. When the team accidentally finds the name of the man, they learn that the murders are connected. Capt. Brass, Grissom, Sara and Greg investigate the death of Raymundo Suarez, who worked at a chicken processing plant owned by Mannleigh Chicken. The foreman tells them that the electrical current was off when the accident happened and Greg and Grissom discuss what might have happened. The team interviews the workers and Mannleight becomes the main suspect since his wife was cheating him with Raymundo. But when Greg finds a miniature crime scene in the room, they change their line of investigation.
"Loco Motives" is an episode with three episodes, two of them entwined. The story of the unlucky Max is tragicomic in every aspect. The miniature of the crime scene of the chicken processing plant is another chapter of the miniature killer. My vote is seven.
