I just realized something after watching last episode: Quinn is the son of the Trinity killer.
Now hear me on this. Quinn came from a previous family raised by the Trinity killer. Something happened to that family that led to him being taken into foster care and adopted by another family. When the Trinity killings began in Miami, Quinn recognized it as his father’s work from his childhood memories. Quinn becomes very concerned by this development because if the cops do catch the Trinity killer, his arrest would bring up a lot of stuff from his past including the family connection between him and Quinn. The reveal of such a connection would destroy Quinn's career and the life he’s built for himself.
So that’s why he was so against the idea of believing that the Trinity killings are really Trinity killings. But his comments weren’t enough to stop Lundy’s interest. So he tells his reporter girlfriend on purpose about Lundy’s investigation, knowing it would be leaked to the press creating trouble for the police and forcing LaGuerta to severe Lundy’s access to police resources. But Lundy still continued his investigation regardless. With the fear of his secret being found out building on him more and more, Quinn came to a point in which he felt a more drastic measure needed to be taken.
He was the one who shot Deb and killed Lundy. He shot Deb to prevent her from recognizing him and to get her out of the way since he was only there to get rid of Lundy. For a moment, Quinn thought he was free of all of this with Lundy’s murder being pinned as one of the Vacation Murders. But that momentary relief was crushed when Deb shares with him her suspicions that the Trinity killer was the one who shot her. Deb will begin her own investigation into the Trinity killer, whether the police disapprove of it or not. Now Quinn must decide what to do to fix this other than killing Deb.
