SANTA BARBARA, Calif. (KTLA) -- DNA has linked the 30-year old murders of Goleta couple to an unknown serial killer suspected in a series of rapes and killings in Sacramento, Ventura and Orange counties.
Thirty-five-year-old Cheri Domingo and 27-year-old Gregory Sanchez were killed in their Goleta home in July 1981.
Santa Maria Times, DNA samples from the Goleta murders were matched to several other cases involving the man dubbed the "Original Night Stalker" and the "East Area Rapist."
Crime technicians analyzed more than 50 pieces of evidence in the slayings of Domingo and Sanchez.
The samples, including a semen stain, yielded small amounts of DNA that had degraded over time.
They were transferred to a law enforcement DNA lab in Richmond, Calif., and matched to samples from four cases involving the Original Night Stalker.
With recent advancements in DNA profiling methods, it was important for us to push forward and reevaluate evidence in this case before it deteriorated and became useless, said Santa Barbara County Sheriff Bill Brown.
The last known attack was in 1986.
Investigators don't know if the killer is still alive.
The Original Night Stalker is different from Richard Ramirez, the serial killer known as the Night Stalker, who is on death row at San Quentin State Prison.
