Luigi Mangione, the suspect in the killing of UnitedHealthcare CEO Brian Thompson, reportedly struggled with chronic back pain and cognitive challenges prior to the incident, as revealed through his Reddit posts. Following a major spinal surgery last year, Mangione shared his recovery journey online, offering support to others with similar conditions. His posts focused on overcoming physical pain but lacked any references to resentment toward the health insurance industry at the time.

However, after his arrest, law enforcement discovered a handwritten note expressing anger toward health insurers, describing them as “parasites” exploiting the healthcare system. During his first court appearance, Mangione shouted accusations about health industry corruption, calling it an “insult to the intelligence of the American people.”

Authorities are investigating whether his deteriorating mental health and unresolved grievances may have played a role in the tragic events leading to Thompson's death. The case underscores the complex intersection of personal struggles, mental health, and broader societal frustrations.
