CSI Miami is primarily a work of fiction. The storylines and characters are created for entertainment purposes. While it could incorporate elements that are similar to real crimes, it's not directly based on specific true events.
A true CSI story that really stands out involved a burglary where the thieves were very careful not to leave fingerprints. However, the CSI team found some microscopic fibers on the broken window frame. They analyzed these fibers and determined that they came from a specific type of clothing. They then went through CCTV footage from nearby stores that sold that type of clothing. After hours of viewing footage, they identified the suspects based on the clothes they were wearing.
One CSI story based on a true story could be about a serial killer case. Detectives used forensic evidence like DNA found at the crime scenes to track down the killer. The real - life aspect might involve the painstaking process of collecting and analyzing evidence, just like in the CSI shows.
There might be a case where a series of arsons were occurring. The CSI investigators used forensic science to analyze the accelerants at the crime scenes. They also interviewed witnesses and used surveillance footage to track down the arsonist. Through careful examination of the burn patterns and residue, they were able to identify the type of device used to start the fires and ultimately caught the culprit.
There was a true CSI story where a body was found in a forest. The CSI team immediately started looking for evidence. They found some footprints near the body. By measuring the size and the pattern of the footprints, they could estimate the height and weight of the suspect. Later, they found some skin cells under the victim's fingernails which led to a DNA match and the arrest of the killer.
