Brian Thompson was laid to rest at a private funeral service in his Minnesota hometown on Monday. That same day, Luigi Mangione was arrested in Pennsylvania and charged with murder in connection to the UnitedHealthcare CEO’s death.

Luigi Mangione, 26, was arrested in Altoona, Pennsylvania, on weapons charges, the NYPD commissioner said. Officials expect charges to be filed in New York soon.

Prosecutors at the Manhattan District Attorney's Office have begun presenting evidence to a grand jury as they work to secure an indictment against Luigi Mangione.
