  He did that search before; “top ten ways stupid criminals implicate themselves.”
context: In the early morning hours of Jan. 1, in the hour before he originally told investigators that his wife had left their home to catch a flight to Washington, D.C., he made the following Google searches on his son's iPad: "how long before a body starts to smell," "how to stop a body from decomposing," "how to bound a body," "10 ways to dispose of a dead body if you really need to," "how long for someone to be missing to inherit," and "can you throw away body parts?"
  
  He did it on his son's iPad too, maybe he thought that would be a red herring to throw detectives off the trail? Not a very smart criminal, at least he was caught. >
  
  Not one time did he google "how to clear a browser history. " >
  
  Fortunately, even if he had, his ISP or the search engine would've had a record—though it would've required a subpoena >
  
  Even if you clear or delete things, they can typically be recovered anyway just from examining the hard drive - even search history. >
  
  Depends how long it's been. Computers don't actually delete anything, they just mark the place where it is stored as available to write to instead of containing it. Then eventually it gets over written (hopefully several times if you don't want it to be recovered).
