I talked to the FBI down there and they said it's something bad happened to him. If he had cash on him and somebody met him and wanted to steal him.

They wanted to steal his cash and they killed him. They could take him out and dump him in the deserts. But somebody knows something.

Somebody has to know something because Mark was real well connected to people who are very well-wifed.

In our goal is to locate Mark. Robin is a Mark's last surviving relative. He had a sibling that passed away early and he had his both his parents have passed since past.

And now Robin is left to wonder where Mark went and our goal is to provide as many answers as possible to help locate Mark and provide resolution.

It's been known about two years and two months since his disappearance and we're seeking out health and assistance from the general public.

Back in September of 2016, 53-year-old Mark Sheer was living alone with his cat in Phoenix, Arizona. His sister Robin and some of Mark's friends began to notice that they hadn't heard from him recently.

They attempted to contact him but he wasn't returning their phone calls. That's when they started contacting each other to see if anyone else had heard from him but no one had.

They went out to his house and a few things seemed out of place. His porch light was left on which was unlike him and his male had been piling up.

Worried that he could be inside and possibly had a medical emergency, they contacted the local police to come out and do a welfare check.

They went inside but there was no sign of Mark. The police took a missing persons report and this is when the police realized that Mark's motorcycle had been found abandoned several miles away.

In the days before he had been reported missing. That was just the beginning of this very bizarre mystery. Over two years have passed and they still have no clue what happened to Mark.

Back in October of last year I traveled to Phoenix to attend their annual Missing Person's Day event. While I was there I had the pleasure of meeting Mark's sister Robin and also the detective who was investigating his disappearance.

Mark's case hasn't gotten a whole lot of media attention so Robin was hopeful that we could help spread awareness about his disappearance.

To understand what may have happened to Mark we have to go back. Robin told us a bit about her brother.

He was a little kid. I mean he was involved in sports from early on and played football in high school and he loved we would go skiing. We grew up in Ohio so we spend a lot of time skiing and he just loved that.
