So I am back in fourth all these years. One day I am super sad. The next day I'm super mad. The next day I don't know is my son alive. I'm so happy.

I don't think he is, but maybe he could be. Maybe the police are right. And I have half the town saying that he's alive and my close friend saying, I'm not sure.

Then I have other really, really close friends saying, Monica, you know him. He would not do this to you.

You know, I'm bouncing back in fourth all over the place like a tennis ball. It's like, and I mad at him and I supposed to be mourning him. How am I supposed to be acting here? How do I deal with this?

And it was just every day I just put my feet on the floor and said, I've got, you know, I've got to look for him. I've got to do something. I've got to do something to help this investigation along because nobody else used one help me.

On September 30, 2011, 18-year-old Nico Leese went missing.

Nico was last seen in Addison, New York with his friend, Robert Knight. It has been reported that Nico and Robert went to Nico's uncle's house around 2pm that afternoon.

Nico told his uncle that he and his friend were heading to Buffalo, New York to go camping.

The pair were driving a pickup truck that they claimed belonged to Robert's grandfather. But this would later be proven to be untrue.

The following day on October 1st, Nico spoke to one of his family members via telephone. Little did they realize that this would be the last time they'd speak with him.

A few days later, on October 3rd, Nico's mother Monica got a letter in the mail that contained Nico's driver's license.

According to the note attached to the license, it had been found in Hornel, New York, which is about a 20-minute drive from where Nico and his family lived.

Nico's family was already concerned, given the fact that they had not heard from him for a few days.

Receiving his driver's license in the mail sent them into a panic.

Nico Leese was reported missing on October 5th, 2011.

It was later found out that the friend that Nico had been with around the time that he went missing had allegedly been dropped off in Romulus, Michigan on October 1st by Nico.

But no one witnessed this drop off to confirm that Nico was there.

Once police started looking deeper into this case, it was discovered that Nico's last cell phone ping hit a tower in Franklin, Tennessee.

He may have been spotted in that area, but there's no concrete evidence proving that it was actually him.

On October 8th, Nico's friend Robert Knight was questioned by police in Michigan in regards to Nico's whereabouts.

Police took Knight to the hospital to get a psychiatric evaluation due to the behavior he was exhibiting.
