Fans believe Jim Hopper (David Harbour) could be back for the fourth season of 'Stranger Things' - and they have proof!

In the final episode of season 3 of 'Stranger Things', Chief Hopper seemingly died in a lab explosion.

Mind you, his body was never shown. Moreover the post-credit scene revealed the Russians have an American in captivity inside a military base.

Now there's still more evidence that Hopper lives.

A fan spotted the character's police car on the 'Stranger Things's set in Georgia and shared it on Reddit.

Filming has just begun on the show's recently renewed fourth season.

There is no release date for the new season just yet.
