A Fairfax County jury imposed two death sentences on Alfredo R. Prieto, 44, hispanic, for the December 4, 1988 murders of Rachael A. Raver and Warren H. Fulton III. The jury was told that Prieto, a serial killer, also already had been sentenced to death for a 1990 rape and murder in California, and that he was linked by DNA to a fourth slaying, in Arlington in May 1988. But they were not told that ballistics tests link Prieto to a fifth homicide, in Prince William County in 1989. Nor did the jury learn that authorities in California are now linking Prieto to four additional slayings there, involving a pair of abductions and double homicides in the spring of 1990. That would bring Prieto's known death total to nine in a span of slightly more than 2 years. Prieto has been incarcerated in California since his arrest there in 1990, and he has been on death row since 1992, for the rape and murder of 15-year-old Yvette Woodruff. In 2005, Fairfax's cold case homicide unit re-submitted the DNA from the unsolved rape and shooting of Raver and the killing of her boyfriend, Fulton. Fairfax Circuit Court Judge Randy I. Bellows will impose the jury's sentence, or reduce it to life without parole, on Dec. 16. In Riverside County, Calif., Stacey Siegrist and Tony Gianuzzi were shot in May 1990, and Siegrist was raped. Their bodies were found in Rubidoux, Calif., the same place where the car used in Woodruff's murder was found. The case remained unsolved until Riverside County Sheriff's Department cold case detectives submitted the DNA earlier this year, and it matched Prieto. In June 1990, in Ontario, Calif., Herbert and Lula Farley were returning recyclables to a grocery store when Lula Farley, 71, was shot to death and Herbert Farley, 65, was abducted. Farley's body was later found in Rubidoux as well. Brown said ballistics showed the same gun used to kill the Farleys was used to kill Siegrist and Gianuzzi. Prieto has not been charged in the 4 newly linked cases.
