In spring 1988 the charred remains of a Porsche on Tucson’s outskirts led investigators to the Champagne-Peters home, where 40-year-old Lili Fiello Champagne and her 17-year-old daughter Melinda Mindy Peters were found shot to death. The vehicle was later identified as belonging to Lili.

A tip from the sister of one of the perpetrators pointed detectives to 19-year-old Richard Harley Greenway and a juvenile accomplice, Christopher Lincoln. Authorities say the pair broke into the house intending to commit a robbery; during the burglary both women were killed. Items were taken from the home and the Porsche was burned, reportedly to destroy evidence. Greenway allegedly told an inmate he shot the victims because they had seen his face.

Both suspects were arrested and charged with murder, burglary, robbery and arson. Lincoln was tried as an adult and received two concurrent life sentences; Greenway was convicted on all counts, including two counts of first-degree murder, and received a death sentence after the court found aggravating factors including financial motive and especially heinous conduct.
