Next month will mark 40 years since Patricia Campbell, 15, and Tina Anderson, 12, went missing in 1978. Although their skeletal remains were later found, their killers are still out there somewhere.

Oneida County Sheriff Arne Jones said they have persons of interest they believe were involved in the girls’ deaths. But they still need more evidence to file charges against them and prove their case in court.

“It’s a matter of gathering the evidence and connecting all the dots,” Jones said. “That’s the frustrating part.”

The case is still active, but investigators haven’t been able to come up with anything new to turn over to the prosecutor. That’s why Crystal Douglas, founder of East Idaho Cold Cases Inc., which aims to raise awareness about unsolved crimes and missing people, is hoping to help.

As the anniversary of Campbell’s and Anderson’s disappearance approaches, Douglas has sent out a public request seeking information about the events that occurred prior to their deaths.

The girls went missing from Alameda Park in Pocatello on July 22, 1978. Their remains were discovered in the Trail Hollow area of Oneida County three years later.

Douglas is trying to gather information that could help recreate their last 24 hours. She is asking anyone who may have taken pictures at the park that day, or who may have details about the girls, where they went, who they were with or the things they talked about in the hours leading up to their disappearance to share that information.

“Did you see them July 21-22? Know someone who gave them a ride anywhere? See or talk to them at the Pioneer Day parade, Alameda park, someone’s house? Did one sleepover the night before? Have a conversation that sticks in your mind a few weeks before they disappeared? Babysit you?” Douglas asked on her Facebook page, “Crystal Douglas (East Idaho Cold Cases)”.

She says she’s just trying to help connect pieces of the puzzle and she needs more details to do that.

Douglas hopes people will be willing to share anything they know, particularly if they’ve never come forward before, if they previously offered information that they think should be reexamined, or if they’ve overheard something odd in recent years.

While she knows it can be difficult for people to speak up, especially if they have suspicions about a friend or a family member, she says it’s better to come forward than to try and keep a secret forever.

“It’s been 40 years this summer and I am not sure the case will ever go to prosecution unless something else comes through for us,” Douglas said. “These girls would be grandmothers now enjoying their own grandchildren. I know the perpetrators have children and grandchildren of their own, and I don’t feel that’s right.”

Anyone with information about Campbell or Anderson can contact Douglas through her Facebook page, “Crystal Douglas (East Idaho Cold Cases),” or email, eastidahocc@gmail.com, she said. They can also contact Oneida County Sheriff’s Office at 208-766-2251 or the Idaho Cold Case Tip Line at 1-844-TIP-4040.

Jones said he appreciates what Douglas is doing.

“Any way we can get new information or evidence is a great idea,” he said. “I support it 100 percent.”
