Cesar Francesco Barone, born in 1960 and raised in Florida, raped and killed four women in Washington County, Oregon, between 1991 and 1993: Margaret H. Schmidt, 61, Martha B. Bryant, 41, a nurse-midwife shot on her way home from a delivery, Chantee E. Woodman, 23, and Betty Lou Williams, 51. He was working as a nursing assistant during part of that period.
He had a long earlier record in Florida, including a burglary conviction as a teenager, and had been a prison neighbour of Ted Bundy on Florida's death row, a connection widely repeated in accounts of the case. He was arrested in February 1993 and sentenced to death in Oregon on January 30, 1995.
He is also suspected in earlier Florida killings that were never charged, which is the source of the plus sign on the recorded toll. Oregon has not carried out an execution since 1997 and a moratorium has been in place since 2011, so the sentence stands unexecuted.
