April 28, 2022 marked 43 years since Christina White, 12, vanished from a friend's home in Asotin.
She's never been found.
Over the years, Asotin County Sheriff's Detective Jackie Nichols has built binders full of information from her investigation not only on the disappearance of White, but also four, possibly five, other local unsolved cases which are believed to be linked to one person.
"My hope in the Christina White case is that a resolution in one of those cases could bring a resolution in the Christina White case," Nichols said.
KLEW News checked with the FBI on the status of these Lewis-Clark Valley unsolved cases between 1979 and 1982.
A spokesperson replied in an email that the FBI remain in close contact with Detective Nichols about Christina White's case, "not ruling out the possibility that her disappearance may be linked to others or may have been committed by the same perpetrator".
Because of her caseload of current and active cases in Asotin County, Detective Nichols spends much of her own time, to this day, investigating the cold cases.
"It's not work for me," she explained.
"I start thinking well what can i do what other avenues haven't we gone down? what can we explore?" Nichols added.
Gloria Bobertz is another person investigating these particular cases.
"You can't give up," she told KLEW News during a Zoom interview from Las Vegas Nevada. Bobertz is a volunteer for the Crescent City, California Police Department helping with missing persons and unsolved cases.
Bobertz is also the cousin of Kristina Nelson, who was one of three people who went missing on the night of September 12, 1982, from the Lewiston Civic Theatre.
Investigators later confirmed that Kristina and her step-sister, Brandy Miller, were homicide victims.
"I won't quit for the victims," Gloria said. "I will not quit. My cousin, Kristie, deserves these answers. Christina White deserves the answers."
Gloria has conducted extensive research about the Lewiston Civic Theatre case as well as White's case, on her own, for about 20 years.
Like law enforcement investigators, she has also found links connecting one person to her cousin's case.
"I have done a lot of research on him, I continue to find things out," she explained.
In both the White and Lewiston Civic Theatre cases, the person of interest had ties.
Detective Nichols knows this information is already out there.
"It's no secret that our person of interest is linked to multiple other cases not only in this area but around the country," she said.
According to the Lewis Clark Valley Serial Killer Facebook page, started by Gloria Bobertz, there is a 1972 case in San Jose, California where the person of interest was arrested for breaking into a mortuary where Antoinette Anino's body was. Her death was ruled an accidental drowning. At the time of the break-in, hers was the only body in the mortuary.
Another cold case believed to have a link to the person of interest was the 1963 murder of Diane Taylor, 8, of Chicago Illinois. Diane was on her way to the YMCA on August 1, 1963. The person of interest was her YMCA youth counselor. Her body was found on August 3, 1963.
However, all of the evidence that has been collected from these cold cases so far is circumstantial.
Detective Nichols explained, in a nutshell, why the person of interest's DNA has not been tested.
"Because they've never been convicted of a crime, a felony-level crime, their DNA cannot be entered into any database," she said.
Gloria echoed the same sentiment.
"We don't have any DNA that's usable right now in any of these cases," she said. "Does that mean law enforcement isn't pursuing it? They're pursuing it. They're looking at it, they're active."
In the pursuit of answers, information is key.
"Don't be afraid," Gloria said. "That seems to be something that I cannot say enough. It's like, if you know something or see something, even though it's just a tidbit, it could be that big huge puzzle piece that we need to get some resolve for these cases."
People can contact Gloria through the Lewis Clark Valley Serial Killer Facebook page.
They can also call Detective Nichols at the Asotin County Sheriff's Office.
Detective Nichols said what keeps her awake at night is thinking about more things she could do to help solve these cases.
"When I lie down to relax when I lie down to relax, then my mind starts thinking of: well what other avenues could we go down is there something we haven't tried?" she explained.
She is encouraged by the advances continually being made by new technology.
"So that keeps the hope alive in me, that we will be able to resolve these cases," Nichols said.
