RICHMOND COUNTY, GA (WFXG) - Its been 11 days.
"We always celebrated everything together. Birthdays, holidays, everything - and every second of today is just surreal, right now. We want my brother back home," his sister, Alaina Cato, told Fox 54s Jasmine Anderson.
And on a day they should be celebrating, his 29th birthday.
"Todays my brothers birthday and even though hes not here with us, he knows and everyone in the community knows that we are celebrating his birthday and we are celebrating him and praying hard for his return, "his sister said.
His siblings are contemplating their next move.
"We will not stop until we find him. We will keep going, even if its months or years down the road - we will not quit," said Curtis Cato, his brother.
Curtis heard from his brother last Saturday - and misses him already.
"Just a happy-go-lucky guy. He gets along with just about everybody. Nobody really was his enemy. He'd give you the shirt off his back if you asked for it. He could fix anything with a Dixie cup and some duct tape.
Curtis flew in from Afghanistan, 7,400 miles, just to search for his brother. His fiancé by his side, he isn't giving up without a fight. Because thats Andrew would do for them.
"Oh yes, I mean. When I say come through - hell or high water," Alaina said.
There is a $5,000 reward for anyone with information that will bring Andrew home.
