The first person who can (by comment to this post) explain the interrelationship amongst these seemingly unrelated things and events will win a brand new AirLINK USB WiFi adapter with +10 dBi antenna:

• Casa Tranquila, a luxury home in Playa Flamingo, Costa Rica (right up the road from yours truly);
• A “ponzi scheme” (a term very much in the news lately due to Bernie Madoff and others);
• The 2004 death of a 21-year-old Miami University student in Florence, Italy for spring break.  (The student and a female friend followed a woman into the private park of her villa late at night and were confronted by the woman’s father.  Apparently, the man thought the student and his friend were thieves and yelled at them to leave in Italian.  When the student, who did not speak Italian, did not immediately leave, the man stabbed him to death); and
• Polaroid Corp., which recently filed for bankruptcy protection.

Good luck.
