What happened to Sam Witwicky?
Transformers: Age of Extinction picks up five years after the Battle of Chicago in Dark of the Moon.
are now being hunted by the CIA and a Cybertronian bounty hunter.
Bumblebee is apparently no longer Sam's guardian, as
the Autobots are all hiding.
No mention, however, is ever made of the Witwicky family even though
they would be the humans most likely to be able to locate the Autobots.
Out of universe, the absence of the family is simply due to the cast change. Is there an in universe explanation as to why there is no mention of the family at all? Perhaps something in a tie-in comic, novel or just an interview?

In Transformers: The Last Knight it's intimated that Sam was one of the few remaining Witwiccans.
However, emphasis on was, as Sir Edmund Burton indicated a couple times (once to Cade and Vivianne, once to the Prime Minister) that he himself was the last Witwiccan (except maybe Agent Simmons, now).
This seems to indicate that Sam Witwicky, descendant of Archibald Witwicky, has died since his last appearance. Perhaps during the Witwicky Incident mentioned in the interview covered in Hypnosifl's answer (pure speculation, of course, but it seems he's toast, regardless).
