Topock, Arizona: The Mohave County Sheriff’s Office has released publicly information received from the Mohave County Medical Examiner’s Office regarding the human skeletal remains of missing person Nancy Hartz.
According to the Mohave County Sheriff’s Office, on May 1, 2019, human remains were located in a remote desert area of Topock. Detectives with the Mohave County Sheriff’s Office responded to the scene, where multiple human skeletal remains were located. The Mohave County Search and Rescue Division also responded to the area, and located additional human skeletal remains believed to be from the same person. The human remains were collected by the Mohave County Medical Examiner’s Office, where they were later sent to the University of North Texas Center for Human Identification for scientific examination. On November 3, 2020, a profile was created for the unidentified human remains, and on December 15, 2020, the human remains were positively identified as previously reported Missing Person, Nancy Hartz.
Nancy Hartz was reported missing on July 28, 2015 by family members, and was last reported to be seen with a male subject from Lake Havasu City, Arizona. Through an investigation into the disappearance of Nancy Hartz, Detectives with the Mohave County Sheriff’s Office learned that the male subject last seen with Nancy Hartz was Robert Lawson Carnochan, who had been using multiple aliases. Robert Lawson Carnochan was arrested on April 13, 2016, for 3 counts of Fraudulent Schemes and Artifices, 3 counts of Theft, 4 counts of Forgery, and 3 counts of Theft of a Credit Card, all unrelated to the death of Nancy Hartz. Robert Lawson Carnochan was later convicted in reference to the above charges, and sentenced to 16 years in the Arizona Department of Corrections.
On December 15, 2020, after positively identifying the human remains as belonging to Nancy Hartz, it was also learned that Robert Lawson Carnochan died in prison on September 17, 2020. Robert Lawson Carnochan was the main suspect in the disappearance of Nancy Hartz, but there was insufficient evidence to connect Carnochan to her death without first locating her body.
On February 11, 2021, the Mohave County Sheriff’s Office received the Mohave County Medical Examiner’s Office’s Autopsy Report for the human remains of Nancy Hartz, along with the Forensic Anthropology Report in reference to the scientific examination of the human remains of Nancy Hartz. Based on the information contained in the report, it was determined that the “Cause of Death” of Nancy Hartz was gunshot wounds, and the “Manner of Death” was homicide.
Since Robert Lawson Carnochan died in prison, no arrest can be made in reference to his involvement in the murder of Nancy Hartz. As of this time, Robert Lawson Carnochan is also the suspect in the disappearance of missing person Neva Jane Lindley, and missing person Verna Clayton, but they have not been located as of this time.
