Lopez has acknowledged that he helped decide to take an organ intended for one patient and use it for another more than 50 places down the waiting list — a serious violation of transplant rules that prompted the hospital to shut down the program.
At issue was what role Lopez may have played in an extensive effort to hide the breach.
The Los Angeles hospital initially reported the name of the actual recipient to the United Network for Organ Sharing, which oversees transplantation nationwide. But later that day, the transplant staff retracted that notification and reported — falsely — that the liver had gone to the man for which it had been offered.
The hospital continued to file falsified documents, including a pathology report describing the liver that was supposedly removed from the intended patient.
Prosecutors alleged that Lopez, 56, had orchestrated the coverup. In an eight-count indictment, he was accused of conspiracy, concealment of material fact and falsification of records.
