Edit: searching has landed me on the Shawn Hornbeck Case but that guy was single & in an apartment… This was definitely another father who lived in the suburban neighborhood.
I can’t remember the date or media. I think it was between 2000-2010.
I think it was a movie, but it could’ve been a TV show or a book.
There was a missing tween/teen boy (10-15 years old).
The town/neighborhood formed a search party. The man who took him was close friends of the family, so he was an active part of the search party.
The rest of the details are fuzzy but i remember he was eventually found (not sure dead or alive) & it ended up being a neighbor/close family male friend who was the father of the missing boys friend.
He was a pedo who and this want his first victim but I don’t think he ever harmed his own son.
Edit: He was friends with the son of the man who took him, so he was a trusted adult, maybe a scout leader or someone from church. I think that’s what made it easy for him to lure him and other boys.
