A reward is up to $10,000 for information leading to AJ Lufkins.
The Sisseton man was last seen at the American Legion Hall in Sisseton nearly three months ago.
Tonight his family expressed their frustration in figuring out where their son, grandson and friend is.
"Not a day goes by I don't think about him," says Lufkins' grandfather Carl Lufkins.
He was one of several family members announcing tonight the reward for information leading to his missing grandson is now up to $10,000.
Tonight the family says more than anything, they want some answers.
"How the investigation is going - anything. I haven't spoke to anybody for about a month now so I don't know how it's going," says AJ's mother Sheila.
She says she first reported her son missing in April.
But she says two weeks later she found out the case wasn't in the tribal police system.
"I was really angry because I reported it, the city told me I had to report it with the tribe."
Sheila says nothing was done.
"Just that one day they searched when he first disappeared," says Carl Lufkins.
The family says it's not like AJ to just take off with no clothes or possessions.
And they're waiting for the information that will give them closure.
His mom Sheila says, "We just want information to bring him home."
Money for that $10,000 reward was collected from fundraisers, donations and the Sisseton-Wahpeton Tribal Secretary.
