Most Americans believe health insurance profits and coverage denials share responsibility for the killing of UnitedHealthcare’s CEO — although not as much as the person who pulled the trigger.

In the survey from NORC at the University of Chicago, about 8 in 10 U.S. adults said the person who committed the killing has “a great deal” or “a moderate amount” of responsibility for the Dec. 4 shooting of Brian Thompson.

Despite that, some have cast Luigi Mangione, the 26-year-old suspect charged with Thompson’s murder, as a heroic figure in the aftermath of his arrest, which gave rise to an outpouring of grievances about insurance companies. Police say the words “delay,” “deny” and “depose” were scrawled on the ammunition investigators found at the scene, echoing a phrase commonly used to describe insurer tactics to avoid paying claims.

UnitedHealthcare has said Mangione was not a client.

About 7 in 10 adults say that denials for health care coverage by insurance companies, or the profits made by health insurance companies, also bear at least “a moderate amount” of responsibility for Thompson’s death. Younger Americans are particularly likely to see the murder as the result of a confluence of forces rather than just one person’s action.
