Disappearance of Patricia Spencer and Pamela Hobley

Hobley's dental charting and both subject's DNA profiles were obtained and were used to compare against unidentified decedents. Neither of the girls have fingerprints on file, and Spencer's dental records are also unavailable. As they neglected to carry any form of identification, physical data such as dental records and DNA would be needed to identify their bodies, if they were to be found. A new detective was assigned to the case in 2010 and proceeded to interview witnesses again in hopes to uncover new information about the case. In 2013, police released a statement indicating they had a person of interest in the case, but they still needed additional information for the case to continue.

In 1985, police were told that the two were murdered by "two area men" and buried near a barn, noted to be a popular location for teenage parties. Decades later, the local chief of police directed an investigation of this suggestion and a search of the area, with aid of cadaver dogs, which turned up no detectable evidence that human remains were at the scene. It is unknown if the man that owned the property at the time has been considered a person of interest. Other places that were known to be frequented by teenagers were also searched to no avail.

Patricia Spencer and Pamela Hobley were two American teenagers who went missing on Halloween, Friday, October 31, 1969 in Oscoda, Iosco County, Michigan after presumably committing truancy together, as they had both been seen walking in each other's company shortly before. The pair were aged 16 and 15, respectively, and "were not considered friends" at the time they disappeared. Their bodies were never recovered, yet it is believed by authorities that both of their lives had ended with homicide.

Pamela Sue "Pam" Hobley was fifteen and was born on May 24, 1954. Her hair and eyes were brown, and she was between 5 feet 6 inches and 5 feet 8 inches tall and weighed about 110 to 115 pounds. She had "distinctive marks," namely two scars, one near her nose and the other by her mouth, although some sources state the latter was a birthmark. Hobley wore a white imitation fur coat edged with brown, a plaid skirt, a shirt of an unspecified color, high-heeled shoes, and white socks. It is known that Hobley had been engaged in activities of which her family did not approve. Rumors also have circulated that she, along with Spencer, may have "experimented with drugs and alcohol." Hobley had apparently accepted a marriage proposal prior to her disappearance.

Patricia Ann "Patty" Spencer was 16 at the time she went missing, born on January 10, 1953. She was estimated to be between 5'3"-5'4" tall and weighed between 120 and 145 pounds. Her eyes were blue, her hair was brownish-blond, and she wore glasses, although she didn't have them on October 31. When last seen, she wore a brown pullover with a matching skirt and a pair of high-heeled shoes. A jacket with a "gray and green plaid" design and a necklace decorated with a peace sign was also in her possession. She had at least one known scar, due to a dog attack on one of her legs.
