Luigi Mangione retained prominent attorney Karen Friedman Agnifilo to represent him on New York charges in the murder of UnitedHealthcare CEO Brian Thompson.

The firm, Agnifilo Intrater LLC, confirmed Friedman Agnifilo will represent him but declined to comment further.

“She will not be making any statements at this time,” the firm said in a statement.

The dayslong manhunt for the shooter ended Monday when Mangione, 26, was arrested in Altoona, Pennsylvania, where he was found eating at a McDonald’s restaurant and carrying a backpack containing what authorities said was evidence linking him to Thompson’s shooting.

Mangione, who comes from a prominent Baltimore family, was charged in New York with one count of murder, three counts of criminal possession of a weapon and one count of possession of a forged instrument.

Friedman Agnifilo was the chief assistant district attorney in the Manhattan District Attorney’s Office under Cyrus Vance Jr. for seven years. She also served four years as the chief of the office’s trial division.
