Perhaps he should have Googled a few red herrings…
A San Francisco-based investment banker learned the hard-way not to post-meditate his crimes. After accidentally killing 55-year-old Gurdeep Kaur during a drunken hit-and-run, Lee Harbert went home and Googled himself guilty.
Although Harbert told the police he believed he hit a deer (in San Francisco?), police were able to prove otherwise by searching his PC. His Google search history showed search terms such as “auto parts, auto dealers out-of-state; auto glass, Las Vegas; auto glass reporting requirements to law enforcement, auto theft,” among other incriminating inquiries.
The gem that makes this perfect for an Encyclopedia Brown novel? Harpert searched for the term “hit-and-run” and then followed the link to a story about the crime he had committed.
