The person of interest identified and detained Monday in the apparent assassination of UnitedHealthcare CEO Brian Thompson was revealed to have deep ties to the state of Maryland with family businesses in Baltimore and a family member in state government.

Authorities identified Luigi Mangione, a 26-year-old former Ivy League student, as a person of interest in the fatal shooting of UnitedHealthcare CEO Brian Thompson, The Gateway Pundit reported Monday.

It was later discovered that his family owns multiple businesses in Baltimore City or Baltimore County, including Hayfields Country Club in Cockeysville.

He is also a cousin of Republican State Delegate Nino Mangione, who has been in office since 2019.

A source in Baltimore County who is indirectly familiar with the possible shooter described him as “super smart” and said the family is “very well off.” Some locals have rumored that Luigi Mangione had a bad injury and was a disgruntled client of United Healthcare or that he had a close family member who was wronged by the health care system. “But who knows,” said the local.
