May 25 is National Missing Children's Day, when we remember missing children and the families who love them. Charles "Arlin" Henderson disappeared on July 25, 1991.
Nearly 25 years later, Arlin's mother continues to hope and pray for news about her son.
Debbie Henderson-Griffith is Arlin's mother.
"Sometimes it seems like just yesterday and sometimes it seems like forever," says Griffith. "Especially when I look at the update pictures I get sent."
Arlin disappeared on a July evening while riding his bike near his home in Moscow Mills, Missouri. The search to find him was extensive. Volunteers blanketed Lincoln County for days, looking for any trace of the boy.
"I don't know what to think anymore," says Griffith. "I don't think anyone should have to go through what I've gone through."
She's gone through years of leads that ended up going nowhere.
"When they found the bike I thought, 'Alright now we've got answers, we'll know what happened,'" says Griffith.
But it wasn't to be.
"There's a reward out, as hard up as money is, you would thought somebody would come forward, but they didn't," says Griffith.
She says the pain of not knowing is almost unbearable.
"You never forget, you go to bed at night and it's the last thing on your mind," says Griffith. "And you don't like to talk about it."
She knows in heart that someone knows what happened to Arlin.
"It's not like he just vanished and you know people talk," says Griffith. "There's someone out there that knows something, I just wish they would come forward and tell what they know."
It's a message she hopes someone will hear, bringing her the closure she's wanted for the past 25 years.
"I think that every mother who's lost a child needs to know that maybe they're not being forgotten and maybe someday somebody will do something," says Griffith.
The Lincoln County Sheriff's Department has investigated hundreds of leads, but right now the case is cold. Anyone with information on the disappearance or whereabouts of Arlin are asked to call the Lincoln County Sheriff's Office at 636-528-8546.
