Earlier that morning she had been dancing at Plumbers Hall, 5841 Newman Court in East Sacramento, with her last sighting alive at 43rd Street and 11th Avenue, about 2 miles southwest of Plumbers Hall. This sighting was only 3 1/2 hours prior to her body being discovered alongside Pleasant Grove Road, 15 miles north. It was clearly evident she had been transported to the location she was ultimately found by a vehicle, which investigators surmised would have been heavily bloodstained. Therefore, the location of her murder was considered to lie elsewhere, possibly close to the area she was last seen alive.
Below I have added the relevant locations regarding Nancy's last known movements that morning.
On Tuesday April 22nd 1986, Laotian couple Koy Ien Saechao (48) and Choy Fow Saelee (40) were traveling back on the two-and-a-half hour journey to their residence in Dorman Road, Yuba City after visiting their son in a Merced CA hospital, situated in the area of the San Joaquin Valley of Northern California. They were only 45 minutes from home when it was believed they had opted to take a rest on the roadside edge (or ushered over by a second vehicle), near the interchange of Highway 99 and I-5 Sacramento and attacked without remorse. How the killer approached is open to question, but the assailant unleashed a barrage of gunfire into their car blowing out both front side windows, testimony to which, was the 15 small caliber shell casings scattered and retrieved from beside the vehicle. The couple suffered multiple shots to the head. Two weeks later, a letter arrived at the San Francisco Chronicle purportedly from the Zodiac Killer laying claim to the savage killings. There were reports in the newspaper that an unidentified "hitchiker" flagged down an East Nicolaus patrol officer and directed him to the murder site, although only describing it as a car accident. In the 1986 Letter the author stated "The Blue Meannies almost caught me", bringing forth the notion he was describing the encounter with the patrol officer and effectively taunting the police.
Sutter Hospital is just two miles from the location where Nancy Feusi was last seen - although it appears the murderer in the respective cases headed in different directions to conceal the body.
Nancy Feusi was last seen at approximately 3:00 am on July 22nd 1973 and discovered at 6:30 am, just 3 1/2 hours later. The journey time by vehicle from 43rd Street and 11th Avenue in Sacramento to Pleasant Grove Road is about 30 minutes, thereby leaving a shortfall of 3 hours. Had she befriended her killer at Plumbers Hall while dancing and met her demise shortly afterwards? Had this been the case, it is likely the murderer headed to somewhere he was sure he wouldn't be spotted while disposing of the body, while minimizing the time he was driving around with a body in the bloodstained vehicle. The fact that he drove just 15 miles to this "out of the way" location, could suggest it was somebody familiar with the area and quite possibly somebody who didn't live too far beyond.
