A former stripper turned filmmaker, Vera Svenchina (pictured above), was caught after she followed a blind Google employee into the search giant's corporate headquarters with the intent of dropping off a book and a note to co-founders, Sergey Brin and Larry Page. 

This would all seem random and crazy if you didn't know about Vera Svenchina's past. Last year, the former stripper filed a report with the Mountain View, Calif. police against Google, accusing the company of sending messages to her brain telling her to kill herself. The police locked her up in a mental ward for three days. 

Then, in February of this year, the billionaire Zynga CEO, Mark Pincus, filled a restraining order against Svenchina. Pincus said she threatened his wife and children and stopped by his home twice a week. She also sent Pincus a series of crazy e-mails and voicemails saying things like, Zynga was her family's idea, and that Sergey Brin and Larry Page killed her father.
