Haunting Evidence: Bringing Crime Solving to Another Dimension
A car belonging to Russian computer expert Sergei Malinka, who has been questioned by police as part of the Madeleine McCann investigation, was destroyed in an explosion in the early hours of March 20, with the word "Fala" ("talk" in Portuguese) written next to it.
"Harry Potter" author J.K. Rowling requested that booksellers display Madeleine's picture next to her latest novel.
Since her disappearance, there have been numerous Madeleine “sightings” across the world, including ones in Belgium, Portugal, Malta, France, Amsterdam and Morocco. Investigators have discounted most of these.
As Kate McCann became increasingly desperate for ideas to find her daughter, British authorities gave her a police manual which provided step-by-step instructions on solving crimes.
The McCanns and the group of friends with whom they dined while Madeleine was kidnapped have been dubbed "The Tapas Nine" by British tabloids.
George Allen Smith
The three men who were the last to see George Allen Smith alive were also alleged to have participated in a sexual assault on the cruise ship three days later. The trio reportedly videotaped the second incident.
When George Allen Smith was reported missing, the cruise ship was abuzz with false rumors, including one that claimed he had recently won the lottery and had been killed for his money.
Royal Caribbean agreed to pay a million dollar settlement to Smith's estate in January 2007.
George Allen Smith and his male friends reportedly were consuming absinthe the night he disappeared. Absinthe can cause a variety of side effects including psychotic behavior, hallucinations, sudden delirium, convulsions, suicide and death.
The night he disappeared, George Allen Smith's wife passed out drunk in a hallway far from her cabin.
The San Francisco Police Department marked its investigation "inactive" in April 2004 but then reopened the case in March 2007. The case has remained open in other jurisdictions.
Although the Zodiac claimed that he killed as many as 37 people, investigators agree on only seven confirmed victims, two of whom survived.
The "Scorpio killer" in Clint Eastwood's "Dirty Harry" was based on the Zodiac Killer.
The Zodiac sent at least 18 letters, usually to newspapers but occasionally to private citizens. Of the four cryptograms the Zodiac sent to newspapers, only one was solved.
With his similar predilection for unhinged letter-writing and a strong background in mathematics and bomb-making, Ted Kaczynski, also known as the Unabomber, was briefly suspected to be the Zodiac Killer. However, Kaczynski lived in Illinois during most of the killings, and was eliminated as a suspect.
Electrical burn marks on JonBenet's cheek indicated that she may have been Tasered before she was killed.
The "ransom" note found by the Ramseys demanded $118,000. This is the precise amount that John Ramsey, JonBenet's father, had just received as a Christmas bonus.
JonBenet's body showed evidence of having been strangled at least twice.
Patsy Ramsey was a former beauty queen, having held the title Miss West Virginia 1977; her sister became Miss West Virginia in 1980.
The autopsy revealed that JonBenet had eaten pineapples only a few hours before her murder, and police photographs of the home reveal that there was a bowl of pineapple on the kitchen table with a spoon in it. Though Patsy's fingerprints are on the bowl, she claims that neither she nor her husband put the bowl on the table or fed the fruit to JonBenet.
