When did John Meehan - screenwriter die?

There seems to be some confusion. There is no record of a screenwriter named John Meehan.

It's possible you're thinking of:

* John Meehan, the subject of the Netflix series "Dirty John", who died in 2016. He was not a screenwriter.

* A different John Meehan, who may have been a screenwriter. If you have any more information about him, like a specific film or TV show he worked on, it would be helpful in finding more information.

Could you please clarify your question?
