(CNN) New York City's chief medical examiner said her office stands by its conclusion that Jeffrey Epstein's cause of death was suicide by hanging.

Chief Medical Examiner Dr. Barbara Sampson's statement follows claims made by a doctor paid by the Epstein family challenging that conclusion.

"Our investigation concluded that the cause of Mr. Epstein's death was hanging and the manner of death was suicide. We stand by that determination," Sampson said.

"We continue to share information around the medical investigation with Mr. Epstein's family, their representatives, and their pathology consultant. The original medical investigation was thorough and complete. There is no reason for a second medical investigation by our office."

The comments come after Dr. Michael Baden, a former NYC medical examiner, claimed on "Fox & Friends" on Wednesday morning that findings in Epstein's autopsy were "more consistent with ligature homicidal strangulation."
