Federal prosecutors said no one from the state or federal government eavesdropped on a jailhouse phone conversation between accused UnitedHealthcare CEO killer Luigi Mangione and his lawyer.
Defense attorney Karen Friedman Agnifilo claimed at a court appearance last week that prosecutors at the Manhattan district attorney’s office had been "eavesdropping" on a call after federal prosecutors provided them with a recording.

"To be sure, no one at [the Manhattan DA's office] or the Government 'eavesdropped' on the defendant on a live basis," prosecutors said in the filing Tuesday. "Rather, consistent with well-known practice in federal and state jails, many of the defendant’s calls are recorded with notice of the recording provided to him and the person on the other side of any calls."

Prosecutors reminded Agnifilo there are ways for attorneys to bypass recorded lines when setting up calls with incarcerated clients and told the judge no further action was needed.
