Murder of Gordon Sanderson

Discovery of the remains

On April 13, 1977, a local couple scavenging for a septic tank pump on their abandoned rural property near Lindbrook, Alberta, made a horrific discovery. They saw a human leg bobbing in the old septic tank and immediately alerted the Tofield detachment of the Royal Canadian Mounted Police. Two officers responded to the scene and spent an hour manually emptying the 1.8 metre deep tank with an empty ice cream pail to recover the body. The decomposed remains were wrapped in a yellow bed sheet and tied with a nylon rope. The victim was wearing a blue Levi's shirt with snap buttons, a grey T shirt, blue jeans, and imitation Wallabee shoes. The location was approximately thirteen kilometres west of Tofield, a small community where the news of the murder horrified its 1,200 residents.

Autopsy and evidence of torture

The initial autopsy in Edmonton incorrectly determined the victim to be Caucasian. The examination revealed Sanderson had suffered two gunshot wounds, one to the head and another to the chest, which were the cause of death. The autopsy also uncovered evidence of extreme and prolonged torture prior to his death. Sanderson had been beaten, tied up, and burned with a small butane torch and cigarettes. He had also been sexually mutilated with a sharp object, an act so severe it took the medical examiner several months to positively identify the remains as male. Burn marks on his shirt sleeves suggested he may have been tied to a bed during the torture. The weapon used for the mutilation could not be conclusively identified, though farm shears were suspected. After death, his body had been covered in quicklime, likely in a mistaken attempt to hasten decomposition.

Early life of Gordon Sanderson

Gordon Edwin Sanderson was an Indigenous man born in Manitoba on October 22, 1950. Police stated that Sanderson was a victim of the Sixties Scoop and was put into foster care when he was nine years old. As an adult, he struggled with addictions and had various encounters with police. In the 1970s, he was living in Edmonton. The last time he spoke to his family, he mentioned plans to visit his brother, Arthur, in Calgary. He was 26 years old at the time of his death. His early childhood illness, noted in his bones and teeth from around age five, was never specified in the investigation.

The initial investigation and forensic efforts

The RCMP investigation initially suspected the victim was a migrant worker not from Alberta. Due to a lack of evidence in the septic tank, police believed Sanderson was murdered elsewhere and the tank was merely a dumpsite. The vicious nature of the killing led investigators to believe his murderers knew him. They also suspected the killers were Tofield locals or familiar with the area, given the rural property's location. The case saw significant forensic efforts over the decades. Sanderson's body was exhumed twice from an unmarked grave in an Edmonton cemetery. In 1979, his remains were flown to forensic anthropologist Clyde Snow and medical illustrator Betty Pat Gatliff in Oklahoma. They created a 3D facial composite and, by measuring his hands, determined he was right handed. Snow also correctly believed the victim was Indigenous and around 35 years old, contradicting the RCMP's initial assessment. The remains were exhumed and reconstructed a second time in 2000 by Cyril Chan of the Edmonton medical examiner's office.

The long road to identification

For 44 years, the victim was known only as Septic Tank Sam or the Tofield John Doe. Despite extensive efforts, including sending X rays of his teeth to 800 Alberta dentists and publishing them in dental magazines, the case remained cold. Retired officer Ed Lammerts, who helped recover the body, spent an estimated one million dollars on the case and thought an identification would never come. The breakthrough finally occurred in 2021 when the RCMP submitted DNA evidence to Othram Inc, a private laboratory in Texas specializing in forensic genetic genealogy. A match was identified in January 2021, turning the case into an active homicide investigation once more. The identity was publicly announced at a virtual press conference on June 30, 2021. Sanderson's identity was confirmed using DNA from his older sister.

Current status of the homicide investigation

Following Sanderson's identification, the Alberta RCMP Historical Homicide Unit and Missing Persons Unit reopened the case as an active investigation. Police have stated they believe Sanderson was killed by associates involved in various criminal acts in the Edmonton area. They acknowledge that the killer or killers may now be deceased, but the investigation remains open. The RCMP continues to seek information from the public and can be contacted via the Tofield detachment. The case highlights the potential of new forensic technologies to breathe life into cold cases and provide long awaited answers to families.

Impact on the community and family

The discovery of the body in 1977 sent shockwaves through the small community of Tofield. Farmers checked their own septic tanks, and business owners worried the murderer could have been a regular customer. There was local speculation that the sexual mutilation was a punishment for a sex crime or infidelity. For Sanderson's family, his disappearance had been a source of pain for decades. The identification in 2021 finally provided closure regarding his fate, though the search for his killers continues. The case also serves as a sombre example of the vulnerabilities faced by Indigenous individuals, particularly those like Sanderson who were affected by the Sixties Scoop and subsequent struggles.
