Brian Thompson, the CEO of major insurance group UnitedHealthcare, was shot to death at point blank range in Midtown Manhattan on Wednesday morning before he was set to attend an investor conference. The masked gunman, who remains on the loose, appeared to be lying in wait and shot Thompson several times from behind, NYPD Commissioner Jessica Tisch said at a news conference.

The motive for the shooting remains unknown, but speculation has surrounded the company’s policy of denying health care to customers as well as Thompson’s impending testimony about the company’s business practices.
