OKEANA, Ohio - As Kristen King’s husband lay dying in their yard from three gunshots to his head, the 911 operator asked her: Did she know who killed him – or why?

Sobbing, King identified the shooter as her neighbor in the small Ohio town of Okeana. “His name is Austin Combs,” she stammered. “He’s come over, like, four times confronting my husband because he thought he was a Democrat.”

Then she broke down. “Why?” King wailed on the 911 recording, struggling for breath. “He’s the love of my life!”

The Nov. 5 killing of Anthony King was among 213 cases of political violence identified by Reuters since the Jan. 6, 2021, attack by supporters of former President Donald Trump on the U.S. Capitol. Three academics who reviewed the cases say they add to growing evidence that America is grappling with the biggest and most sustained increase in political violence since the 1970s.
