The suspect in the killing of UnitedHealthcare’s CEO has added a prominent defense lawyer to his legal team as Manhattan prosecutors work to return him from Pennsylvania to face a murder charge.

Luigi Mangione will be represented by Karen Friedman Agnifilo, who was a high-ranking deputy in the Manhattan district attorney’s office for years before entering private practice.

Friedman Agnifilo’s law firm confirmed late Friday that she had been retained to represent Mangione.

Her husband and law partner Mark Agnifilo is representing Sean “Diddy” Combs in the hip-hop mogul’s Manhattan federal sex trafficking case.
