BOISE - 2 News first talked to Marco Alcalde one year ago, after his then, seven-year-old son Max-Gian disappeared with his ex-wife during the holidays.

Today, his thoughts are still with his little boy.

"Everyday is emotional," Alcalde said. "Some days are a lot worse than others."

Alcalde says he's dedicated the last 356 plus days, to getting Max-Gian back. He's been working with private investigators, the FBI and traveling thousands of miles to Central America, where he believes his now eight-year-old son may be.

"I'm pretty optimistic," he said. "In fact, I have been called a hopeless optimist at times."

Officials believe Max-Gian was taken by his mother, Margaret Dunbar. Alcalde tells 2 News, Dunbar picked up Max-Gian last year the day before Thanksgiving, but she never brought him back home.

"The first things I would say (to Dunbar) are, you are so incredibly selfish," he said.

Max-Gian's room is still decked out in his favorite team's colors. Alcalde says he's trying to make his son's transition as smooth as possible, if and when he returns home.

"I've been told that he could completely snap right back and be just like he never missed a beat," he said. "And then it could also have lasting effects."

Until then, this dedicated dad will be racking up frequent flyer miles.

"You just keep pluggin' and hoping that something is going to happen," he said.

Max-Gian was four feet tall and weighed 55 pounds when he was last seen. His alleged abductor, Margaret Dunbar is about five feet tall and weighs 120 pounds.
