Scrapyard Ambush
In season 4, Harold receives word from Sheila Miller, a member of his wife's congregation who works in the cafeteria at the North Dakota Black Site, that the CIA is planning a meeting with the Maudlings in the scrapyard. The night before the meeting, Harold walks several miles to the scrapyard with a disassembled rifle and a pipe bomb in a back pack. He plants the pipe bomb in the shell of a car and stakes out a hiding spot in the hills nearby to assemble the rifle and spends the night hidden in the bushes. When the meeting happens the next morning, he nearly sleeps through it but wakes up at the sound of Deemlind laughing. He detonates the pipe bomb and gets off several shots at the Maudlings, killing Deemlind before the CIA are able to triangulate Harold's position and kill him with razor drones.

Unbeknownst to Harold, the scrapyard meeting was for negotiating the release of DEA Agent Rashad Jones from Maudling custody. After Deemlind's death, the Maudlings are no longer willing to release Rashad.
