SHAWNEE, Okla. - It's a mystery that has haunted an Oklahoma town for more than 30 years now.
Sgt. Dan Shumaker, with Shawnee Police Department, said, "There's not a day or week go by that we don't think of some of the cases and files we have and Sandy's definitely at the top of the list."
Sandy Rae disappeared in September of 1984. The free-spirited teenager vanished.
Shumaker said, "Sandy was believed to be going to the bowling alley and maybe a party afterward."
The 17-year-old was last seen at a Shawnee bowling alley. Police say she spoke to a relative, made a call and then rushed out.
But what happened next is the mystery. Did someone pick her up? Did she go to a party at Twin Lakes just west of town? Or did she leave alone?
Johnny Price, Sandy's cousin, said, "We feel absolutely, 100-percent she's dead."
Price is Sandy's older cousin, spokesman for her family. He has vowed to never stop looking for her.
Price said, "I'm going to find out what happened to her no matter what we have to do, where we have to go."
He says it has been devastating to not have any answers for 30 years. They have watched as one tip after another has led police to a dead end.
Price says he has a lot of respect for the Shawnee Police Department, but he says the family has been frustrated with their investigation. He believes there are multiple people out there who have the answer as to what happened to Sandy.
Price said, "We do feel like there are a lot of people who were involved in this or who still know what happened who are still in that community."
Sgt. Shumaker said, "You catch yourself sometimes still looking for Sandy."
Shumaker was not in Shawnee when Sandy disappeared, but he says every officer knows about the case and wants to see it solved.
Shumaker said, "There's that expectation that we will find her."
But for Sandy's family it's more than an expectation, it's a determination to find answers.
Price said, "we want to be able to give her a proper burial. We would like for my Aunt Carol (Sandy's mom) to have some peace in her life."
Shawnee Police say while this is considered a cold case they do still actively investigate any lead which comes in.
Sandy's family is now trying to raise $25,000 to hire a private investigation firm that specializes in cases like this. If you would like to donate to their effort just go to their Crowdrise.com page.
