In the fall of 2016, concern grew for 53-year-old Mark Roger Shearer, a male resident of Phoenix, Arizona, after he had not been heard from for some time. The last point of contact with Shearer was on September 28, 2016, in the vicinity of North 23rd Avenue and West Union Hills Drive. His family and friends became increasingly worried about his welfare. When a friend visited his home, they discovered things seemed out of place, initially sparking fears that Shearer may have suffered a medical emergency inside the residence. However, there was no sign of him. This was described as being highly uncharacteristic of Shearer, who was not known to leave without informing anyone. His sister and a friend officially reported him missing on October 1, 2016. The circumstances surrounding Mark Shearer's disappearance grew more troubling as investigators delved into the case. His 2009 Harley-Davidson motorcycle was discovered abandoned a few miles from his home, near 21st Avenue and West Larkspur, with the keys still in the ignition. At his house, friends and family found a scene that added to their alarm; groceries had been left on the counter, and his cat was unfed. Further investigation of his home revealed it to be in a state of disarray, and the trunk of his car had been left open. These details painted a grim picture and suggested that Shearer's disappearance was not voluntary. As the investigation continued, a more complex image of Mark Shearer's life began to emerge. His sister, Robin Shearer, revealed that her brother seemed to be leading a double life. Evidence of drug use was reportedly found in his home, and it became apparent that he had a circle of friends that his family was unaware of. A long-time friend of 40 years, Jeffrey Daggett, mentioned that Shearer had been preoccupied for months with finding a misplaced envelope containing $10,000. This information led his family to fear that elements of his secret life may have ultimately led to his disappearance. The case is considered a suspicious circumstances missing person investigation, and despite the passage of time and features on podcasts like "The Vanished," what happened to Mark Shearer remains an unsolved mystery. Authorities continue to seek information that might bring answers and closure to his concerned loved ones.
