HAMMOND, Ind. -- A doctor from Indiana accused of health care fraud who was captured in Italy after more than five years on the run repeatedly invoked his right against self-incrimination in videotaped testimony during a civil trial involving the death of a patient.

Mark Weinberger invoked the Fifth Amendment more than 20 times during a video played Thursday at his trial in Hammond. Weinberger remains in federal custody awaiting sentencing April 27 after pleading guilty to charges of health care fraud for billing almost two dozen patients' insurance companies for surgical procedures he didn't perform.

Weinberger and a physician assistant are being sued in Lake Superior Court on allegations they failed to diagnose lung cancer in a female patient who subsequently died.

The fugitive surgeon was captured in December 2009.
