I have a stack of flyers and when I see two police officers talking, I'll pull over and go up to them and give them flyers.

I've actually pulled over police officers by flashing my lights and it's kind of an unusual experience to be on the other end of that and pull over police officers.

They've all been quite nice, quite polite and they seem concerned, but oftentimes they seem like this is all new to them.

The city of Westminster, which is where the Hanyuan went missing, they don't work with the media.

When I ask why, he just said that's their policy. It's just so totally out of character.

It's something that every parent fears, and it's a real thing, it's a thousand times worse than even my scariest imagining would be.

On December 19, 2017, Nathaniel Holmes, who had just turned 17 years old, went missing after being dropped off at his new school.

Nathaniel had been attending an online high school program, but just five weeks before his disappearance, he had transferred to Hidden Lake High School in Westminster, Colorado.

Some of his friends were attending Hidden Lake and according to his sister Hannah, they weren't necessarily the best influences, but he did have one good friend named Anthony at his new school.

On the morning of his disappearance, Nathaniel went to the principal's office and said he needed to speak with his friend Anthony.

The principal refused to take Anthony out of class, and shortly after this, Nathaniel walked out of the school and no one has seen him since.

I'm Marissa, and from Wondery, this is episode 151 of The Vanished. Nathaniel Holmes, story.

At the time of his disappearance, Nathaniel lived with his dad Ben, his younger brother, who was 14 at the time, and his 18-year-old sister Hannah.

He also has another older sister who no longer lived at home. With very little support, Ben worked at night while keeping very close relationships with his children.

Ben had sole custody of them after the breakdown of his marriage seven years earlier. They were close and Ben supported Nathaniel when he found regular school to be difficult.

Although a few incidents had occurred in the teenager's life and the time leading up to his disappearance, Ben had no inclination that Nathaniel had any intention of running away. No one did.

His brother and sister, as well as his friends, were not aware that anything was wrong.

I spoke to Nathaniel's dad Ben and his sister Hannah for this episode. Ben told us more about his son.

He's a quiet boy. He's not overly gregarious. He's a musician. He plays bagcates and does an amazing job at it.

I teach bagcates and I've only ever seen one person go as fast as he did to the level he did. It was kind of remarkable.

I've been raising him by myself for, I guess, at that time it was, I have to do the math, but I got full custody of the children after my divorce in 2010.
