How do detectives crack the case nowadays? Forget elementary, Watson -- try Google.
A tip from the Internet giant, which was monitoring John Henry Skillern's email, led authorities to arrest the 41-year old Texas man for allegedly possessing child pornography, according to reports.
"Thank goodness for Google," one neighbor said of the bust, according to KHOU.
The National Center for Exploited and Missing Children processed the tip, according to news sources.
Skillern, a registered sex offender who worked as a cook at a Denny's, is being held on $200,000 bail, the news station reported.
Back in California, Google is not commenting to media. But privacy and Internet experts note that Google has already made it clear that its users have no "legitimate" expectation to privacy, as the Internet giant argued in a recent court case.
It was not immediately clear if Google fingered the child porn via a unique digital "fingerprint" all digital images have, or if another method was used.
