Pennsylvania governor: Reactions to slain UHC CEO are 'deeply disturbing.'

Pennsylvania Gov. Josh Shapiro condemned internet praise for the brazen fatal shooting of UnitedHealthcare CEO Brian Thompson last week in New York City, calling the comments "deeply disturbing."

"Some attention in this case, especially online, has been deeply disturbing, as some have looked to celebrate instead of condemning this killer," the Democratic governor said during a late Monday news conference.

More: The UnitedHealthcare CEO was killed and many had little sympathy. Why?

Since the attack in Midtown Manhattan outside of his hotel where his health care company was holding its annual investor conference last week, a growing slew of posts have praised the suspect, 26-year-old Maryland man Luigi Mangione, for allegedly firing at the 50-year-old father of two in the early hours of the morning.

Many posts and reactions online criticized the health care system and showed little sympathy for Thompson's targeted death, some detailing their own experiences with the insurance company where loved ones passed for lacking coverage. Others glorify and idolize Mangione for the attack.

Bullets found at the scene read "defend," "deny," and "depose", echoing phrases often used to describe tactics by insurers to avoid paying insurance claims, further opening discussion on the shortfalls of the industry. NYPD Chief of Detectives Joseph Kenny said at a news conference that a three-page document found on Mangione after his arrest expressed "ill will toward corporate America."

But Shapiro was clear that violence is not an acceptable solution.

"In America, we do not kill people in cold blood to resolve policy difference or express a viewpoint," Shapiro said. "I understand people have real frustration with our health care system, and I have worked to address that throughout my career."

He added: "But I have no tolerance, nor should anyone, for one man using an illegal ghost gun to murder someone because he thinks his opinion matters most. In a civil society, we are all less safe when ideologues engages in vigilante justice."

The six-day manhunt ended Monday when Mangione was apprehended in Altoona, Pennsylvania after a McDonald's employee recognized him and alerted police. He was charged with murder and a number of other felonies in New York as well as weapons and forgery charges in Pennsylvania.

"In some dark corners, this killer is being hailed as a hero. Here me on this, he is no hero," Shapiro said. "The real hero in this story is the person who called 9-1-1 at McDonald's this morning."
