Tim Noel is the new UnitedHealthcare CEO following the Dec. 4 targeted killing of its former top executive, Brian Thompson, in Manhattan, reports say.

UnitedHealth Group said veteran internal executive Tim Noel will succeed the late Brian Thompson as CEO of UnitedHealthcare, the nation’s largest health insurance company.

UnitedHealth Group (UNH) announced a new chief executive officer for its health insurance unit, UnitedHealthcare, Thursday, filling the role after Brian Thompson was shot to death last month in New York City.
