Evidence, clues

In some cases, witnesses claim that they saw the Zodiac Killer. Bill Crow, a witness, says that someone driving a white Chevy drove past them stopped and backed up. (http://crime.about.com/od/history/a/zodiackiller.htm). In the Jensen and Faraday killing, 45 minutes before they were murdered Bill Crow was at the same place when this incident happened. Bill Crow lost the Zodiac at an intersection. Later on, Betty Lou Jensen and David Faraday were murdered. The Zodiac Killer enjoyed going after young couples that were alone, in that case he targeted them. Zodiac had shot both of them, but David was still alive yet he died on the way to the hospital. At one point through all the altercations the Zodiac Killer wrote a letter to the Newspaper ordering everyone in that are to wear his symbol on their clothes. He was ahead of the game making more difficult for the police to catch him. Two police officers actually talked to him face to face after tracking a phone call to that location. At that time the Zodiac Killer was thought to be African American. The Zodiac Killer had then gotten away with ease. The police tried to specify how the man they had encountered looked and was perfectly matched to the descriptions that others had made. He sometimes would leave proof on his letters letting everyone know that he was making actual killings. For example, when he killed the cab driver he took a piece of his shirt with blood on it. The Zodiac Killer is still on the loose.
