not from Alberta, but most likely worked as a migrant worker. Due to a lack of evidence in the septic tank, Sanderson was most likely murdered elsewhere and the septic tank was only a dumpsite. Sanderson's murderers are believed to have known him, due to how viciously he had been killed. It is also suspected Sanderson's murderers were Tofield locals or were familiar with the area, due to the location of Sam's dumpsite being on a rural property. Sanderson's body has been exhumed from his unmarked grave in an Edmonton cemetery twice. In 1979, Sanderson's remains were flown out to Clyde Snow and Betty Pat Gatliff, Forensic anthropologist and medical illustrator at the Federal Aviation Administration in Oklahoma who had been creating 3D facial composites from skulls since 1967. Along with creating a facial composite for Sanderson, the two could tell by measuring his hands that he was right-handed. Snow believed Sanderson to be of Indigenous origin and around 35 years old, contradicting the RCMP's belief of Sanderson being Caucasian and between 26 and 32. Sanderson was exhumed and reconstructed for the second time in 2000 by Cyril Chan, who was with the Edmonton medical examiner's office at the time. Aftermath The 1,200 residents of Tofield at the time were horrified to hear of Sanderson's murder. Farmers checked their own septic tanks for bodies and business owners worried that Sanderson's murderers could have been regular customers. Many speculated Sam had been sexually mutilated due to committing a sex crime or being unfaithful in a relationship. Ed Lammerts, one of the officers who helped recover Sanderson's body, has since retired. He believed Sanderson would never be identified, despite sending X-rays of Sam's teeth to 800 Albertan dentists coupled with publishing them in dental magazines, and spending $1,000,000 CAD on the case. Current investigation Police believe Sanderson was killed by associates of his involved in various criminal acts in Edmonton. They acknowledge that his killer may no longer be alive. Identification On June 29, 2021, it was reported that the remains had been identified via genetic genealogy, 44 years after his discovery. Police had submitted DNA to Othram, Inc., a private laboratory in The Woodlands, Texas, and identified Sam in January 2021, after which the case became an active homicide investigation. On June 30, Alberta RCMP publicly identified Sam in a virtual press conference as Gordon Edwin Sanderson, a 26-year-old Indigenous man
