In the summer of 1993, a 30-year-old man named Fred William Conklin vanished from his life in Tucson, Arizona, leaving behind a young son and a mystery that would linger for years. One of the last confirmed times anyone in his family saw him was when he spent a day with his five-year-old son, who was living with his mother. Conklin treated the little boy to a movie and a trip to the toy store, creating a memory that would become the final goodbye. After this outing in June or July of that year, Fred Conklin was never heard from again, and all contact with his family and friends ceased, sparking concerns for his welfare.

For three years, the case grew cold, with no solid leads to explain what had happened to Conklin. Then, in May 1996, the investigation took a significant turn when authorities received a crucial tip. The information pointed directly at Conklin's roommate, Jeffrey Davis, suggesting that Conklin had met with foul play inside their shared residence on west Picture Rocks Road. Investigators began to piece together a grim narrative, believing that an argument over money and drugs had escalated to a fatal confrontation. The theory that emerged was that Davis had shot Conklin in the back during this dispute. This information shifted the focus of the Pima County Sheriff's Department from a missing person's case to a homicide investigation.

The allegations led to the arrest of Jeffrey Davis in March 1997, and his trial for murder commenced in early 1998. The prosecution built its case not on physical evidence of the crime, as Conklin's body was still missing, but on powerful testimony from people in Davis's circle. Two witnesses, described as friends of Davis, took the stand and testified that they had helped him bury Fred Conklin's body. Another witness recounted a chilling confession, stating that Davis had told him about later digging up Conklin's remains to re-bury them in a different location. Despite the defense's arguments and the complete lack of a body, the jury was convinced by the witness accounts. After deliberating for only three hours, they returned a verdict, finding Jeffrey Davis guilty of first-degree murder.

The conviction brought a measure of legal justice, but it did not bring Fred Conklin home. In the wake of the trial, authorities launched extensive searches for his remains, focusing on mine shafts in the Silver Bell Mountains, but their efforts were fruitless. The case remains a poignant one; although a perpetrator was held accountable for his death, Fred William Conklin's body has never been recovered. The official investigation confirmed suspicions of foul play, leading to a murder conviction, yet the absence of his remains leaves his family without a final resting place to visit and a true sense of closure.
