The cold-blooded killing of Brian Thompson is not the first time UnitedHealthcare has been at the center of a high-profile murder case.
In August 2015, a Virginia reporter and his cameraman interviewed an infamous office worker who filmed him being executed on live TV.
Vester Lee Flanagan II shot and killed reporter Allison Parker and photojournalist Adam Ward, who worked for Roanoke's CBS affiliate WDBJ-TV, before committing suicide.
Footage of the horrifying incident was played on the station's morning news program, and captured at least eight gunshots followed by screams, and a momentary scene of 41-year-old Flanagan raising the gun.
Ward, 27, and Parker, 24, were pronounced dead at the scene.
The woman they were interviewing, Vicki Gardner, survived with a gunshot wound to the back.
Flanagan was fired from the media organization in 2013 for poor performance and disruptive behavior.
He then worked in the UnitedHealthcare call center in Roanoke, where he worked until November 2014.
While there, Flanagan allegedly grabbed a female employee by the shoulder and violently told her not to speak to her again, according to news reports at the time. It is unclear why he ultimately quit performing.
Flanagan posted a video of the murder on his Twitter account and committed suicide during a car chase with police.
Almost six years later, Brian Thompson became CEO of UnitedHealthcare Group.
Thompson, 50, was gunned down on Dec. 4 as he approached an investor event at the Hilton Midtown without any security.
After several days of manhunt, Luigi Mangione, a 26-year-old computer engineer from a wealthy Maryland family, was arrested Monday in Altoona, Pennsylvania, and charged with second-degree murder in Thompson's death. .
