Kentucky soldier, Jason Dinh, is in Austin, hoping to see his six-year-old son once again.
"I want my son back."
He talked to FOX 7 because he wants Noah's biological mother to return the boy.
He says Noah is with Cendy Johnly in Austin.
She has had him since December 23rd and was supposed to return the boy on New Year's Day.
That didn't happen.
Dinh and his wife, Haley, say they have not been able to reach Cendy.
Now, the soldier, who did two tours of duty in Iraq, is dealing with a parent's worst nightmare.
"You just don't want to find them face down somewhere. That's my biggest fear."
"I just worry that he's scared and know what's going on and I don't want him to think this is his fault and that we don't want him. I just want him to come home."
The couple went to Kentucky authorities.
Oak Grove Police tell FOX 7 that a warrant was issued for Johnly for custodial interference.
Its a felony in that state.
The couple is also scared that Noah isn't well without his medications for ADHD.
They say the little boy suffers from depression.
They provided a letter written by Noah's psychologist.
"He's off his medicine as well, that has some, a lot of things of why I am so worried because it does a lot of things to his mind."
The couple believes Johnly's family is helping to hide her and Noah.
But Kentucky authorities say that warrant is good anywhere in the country.
Dinh doesn't want his boy to worry.
He makes this promise to his son.
"Noah, daddy's coming to look for you, I'm going to find you but you know you have our numbers on the bottom on your shoe so anytime you want, you can call, just be brave, daddy's not going to stop."
Noah is three feet, ten inches tall and weighs 46 pounds.
He has a mole on his neck, directly below his chin.
He was last seen wearing blue jeans, white skater shoes, and a gray tee shirt with a skull on it.
The couple plans to stay in Austin for the week.
If you have seen Noah, call 911 immediately.
