Cold Cases

A cold case is a case that hasn't been solved ever since it happened. There are multiple cases that haven't been solved but the majority have because the technology of  Forensics's has been updated in the recent years. Its not very common for some cases to become cold after a long period time because the killer either got away with it or couldn't like the person to the crime or cant find the body. The most famous cold case is Natalee Holloway.
