Middle school girls often tell each other everything. I would love to hear from one of her friends that she used to spend the night at during the time that she went missing. Maybe they would have a clue as to what might have happened?
Yeah, she told quite a few of her school friends that she was running away to Florida. I think they might even know more about her connection to Arthur Slaybaugh. Police think she was murdered and their priority is recovering her remains:

In 2011, investigators decided to reopen the decades old case of Tammie and felt she was no longer alive. Now, investigators believe that Tammie was murdered on the day she disappeared. They have also named a person of interest who is believed to be responsible for what happened to her.

The person according to news reports, is a former corrections officer whom Tammie knew before her disappearance. His name was Arthur Mason Slaybaugh II. He had previously served as a mentor to one of Tammie's friends and she admired him and saw him as a mentor.

Slaybaugh has since passed away. He died of a heart attack in January of 2001. Police indicated he was always a person of interest since the investigation started.

Witnesses who had information came to investigators after Slaybaugh's death. They said they were too scared to reveal the information while he was alive. Based on the accounts, investigators believe that Tammie was heading for his apartment on Brown's Beach near Saratoga Lake that morning.

Investigators have conducted several searches for Tammie's body. They have searched many locations based off of statements given to them by friends of Slaybaugh and a former girlfriend.

The most recent search took place in November of 2017. A field property owned by a relative of Slaybaugh's was searched but no sign of Tammie was found at the scene.
