how did doakes die

James Doakes died in the TV series "Dexter" when he was locked in a cabin by Dexter Morgan after discovering Dexter's secret that he is the Bay Harbor Butcher. Doakes was later found by Dexter's ex-girlfriend Lila West, who decided to protect Dexter by setting the cabin on fire with Doakes inside, killing him. His body was so badly disfigured in the explosion that he could only be identified by his teeth. The official explanation in the show is that Doakes was the Bay Harbor Butcher and blew himself up to avoid arrest, which was actually a cover-up by Lila's actions.
