Mock Crime Scene -- Table of Contents

Crime Scenario- Date: November 8, 2011

Location: South Park, Colorado; a small town on the foothills of the Rocky Mountains.

Details: A teacher at South Park Elementary School called the police on the evening of November 1, 2011 at approximately 17:56. She noticed four boys who habitually were together enter the school after hours. Based on her recollection, she identified all four boys as 4th graders Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick. When the police arrive, they moved into a classroom and found Kenny with a sword through his face. The other three boys, identified as Stan, Carman and Kyle) were standing in the room pointing at Kenny. Kyle turned to the police and shouted, "Oh my God, they killed Kenny! You bastards." The boys then left the room, running. The officers secured the room, collected evidence samples, and sent Kenny's body to the morgue.

At first blush, the scene seems to be some kind of a child' prank gone wrong. Officers immediately bagged the sword, covered the hilt for fingerprint processing, and looked to find and identify any detritus or material around the body, and swabbed for blood. Kenny's blood was typed for further match, and officers asked for a detailed report on any fibers or clothing missing from the body. The police then secured search warrants for all the boys' homes, and collected evidence listed below.

Evidence Inventory -- Evidence was collected in three major categories: D (Drugs), (H) Hair, and (B) Blood. Collection was as follows:Get full Download Microsoft Word File access

D- Samples D1 (Powder from Scene); D2 (from scene), D3 (Victim), D4 (Cartman), D5 (Kyle); D6 (Stan). These samples were taken as part of the scene to see if any traces of the unknown powders or substances could be matched from the scene to the suspects, and/or to establish potential patterns of behavior or substance abuse.

H- Samples H1 (Crime scene); H2 (Crime Scene); H3 (Victim); H4 (Cartman); H5 (Kyle); H6 (Stan). Hair samples were taken to identify potential matches to scene from suspects and to establish their position at time of crime.
