"We were super close. He was a fun, very smart guy. We had a blast together when we were young."
FREMONT, Iowa — Mark Milligan and his older brother Harry Dennis Milligan had a very close relationship growing up.
Unfortunately, that relationship was disrupted in 1984.
On June 30 1984, Harry went out with his friends in Albia, Iowa.
On July 1, 1984, Milligan was reported missing.
He was reportedly last seen heading back to his home in Avery, Iowa.
After not hearing from him for a few days, the family began to worry and question the situation.
"Yeah there was concern on my family's part and my mom and dad's part,” Milligan said. “It got worse as time went by. My brother didn't take off and leave. Something happened."
For years now, Mark has been gathering information about the night his brother went missing.
It is a difficult task to piece all that information together but he doesn't plan on easing up in hopes of finding answers about his brother's location.
"Somebody has to come forward. Somebody has to know something and sooner or later, their moral compass points them in the right direction to say 'okay, I’ve got to say something.' I’m going to keep pushing. I'm going to keep questioning people,” Milligan said. “I'm going to keep digging for information looking for that one little piece of information that tells me where he's at."
Milligan hasn't been alone in the search for his brother.
He started a Facebook page called 'Harry Dennis Milligan Still Missing' and he has received tremendous support from the community.
The Facebook page has worked so well that it has caught the attention of people nationwide wanting to help spread the word.
Milligan is very grateful for all of the support.
"I can't say enough to the community and the people,” Milligan said. “I mean, it's amazing."
At this point, Milligan isn't looking to solve a crime, he just wants his brother back.
"I just want to find him. I want to find him and bring him home. My parents were never able to do that. That's always been my mission is to bring him home."
