I guess all of us would like some closure and I don't know really closure would be nice instead of having an open-ended question mark for the rest of our lives.

This is unfamiliar territory has never been here before.

I just feel like he would have come back. If this was on his terms, he would have come back or reached out or something to see or hear about Kaya.

Because he loved her. I mean, he was a good dad. He did care about Kaya a lot and that was my main factor in turning it in is just the fact that he hasn't even reached out for anything about her.

It's just kind of crazy when people just vanish. It's either like one of two things, it's either somebody did something and they're not coming back or they've just completely dropped and changed their lives.

Yeah, I don't know. I have no idea about Ben.

On July 20, 2017, 30-year-old Benjamin Redfern was planning to travel from his home in Farrington, New Mexico to attend his daughter's sixth birthday party in the nearby town of Aztec, a little under a half an hour away.

Ben and his daughter's mother were no longer together but they were committed to co-parenting their daughter and Ben was known to be a loving father.

By this time, Ben was in another relationship and his current girlfriend was unhappy about him attending the party.

On the way to the party, an argument ensued and his girlfriend stopped the car and let Ben out, far from the party. Ben ended up walking the rest of the way and finally made it there three hours late.

Everyone at the party noticed that Ben seemed upset and had a black eye. Since he didn't have a vehicle to drive home due to what had happened earlier, Ben's dad gave him a ride home.

In the car, his dad pleaded with Ben to come back to California with him. He feared for his son's safety. Ben declined the offer but stated that he didn't want to go back to the apartment he shared with his girlfriend.

After his dad dropped him off, this was when Ben dropped off the radar, which was out of character for him. He didn't go long periods of time without contact with his daughter.

Months later, there was a sighting of Ben but it's unclear what happened to him and his family is desperate for answers.

Amarisa and from Wondery, this is episode 226 of The Vanished, Benjamin Redfern's story.

In a four-part series, The Generation Y Podcast unravels the story of Khalif Browder, a young boy falsely accused of stealing a backpack and held it Recker's island for three years without trial.

This is a story about a young life caught in the middle of the justice system. Listen to Generation Y on Amazon Music or wherever you get your podcasts.

For this story, we spoke with Ben's father Mark. He told us about how he and his ex-wife adopted Benjamin.

He was less than a year old when Karen and I adopted him. We'd already adopted one baby from Korea.

It was the cold day at JFK. We were living in Pennsylvania at the time so we went to New York to pick him up.

We had brought along a snow suit. We were trying to get him into the snow suit and he just simply refused.
