Adrianna HortonTwelve-year-old Adrianna Horton has been missing more than 24 hours from a park in Missouri. The young girl was reported missing soon after being allegedly seen getting into a car with an unknown person. The truck was tracked and a suspect is in custody -- a man Adrianna's father, James Horton, knows -- but there is still no sign of the young girl.

Adrianna's 8-year-old sister was out on the search last night and pleading for help in finding her sister. "Please help find my sister," little Lydia Horton said to reporters. So heartbreaking.

The suspect, Bobby Bourne, 34, is currently being held on $1 million bond in jail and is someone Adrianna's father knew and worked with. In fact, their children played together. See below:

As of now, Bourne is just a suspect. He has been charged, but not convicted. But still. It's disheartening that a person is in custody and there is still no sign of the girl.

Her family and friends say she wasn't the type of girl who would have gotten into a car with a stranger. Since the majority of witnesses are the same age as Adrianna (12), it's hard to nail down exactly what happened.

The family's heartbreaking statements just make it all the more difficult to process. Her father said:

This is the worst feeling I've ever had in my life. I don't know if she's safe. If she's okay. If she's here.

Can you even imagine? As a parent, it's a nightmare scenario and, my God, the ANGER he must feel. It's unimaginable. Her heartbroken grandmother also spoke out:

I’m numb. We are scared to death. We need all the help we can get because I know the longer she is gone, I know how it’s gonna turn out.

There is almost nothing worse in the world than a missing child. The fear and uncertainty is just impossible to even fathom. And this is even worse because it may have been someone the father knew and at least somewhat trusted. Who could do this?

Let's hope and pray that Adrianna is found safe and that her family is spared the heartbreak that comes with these cases when they end tragically. My heart goes out to them.

Do you tell your kids about people they know as well as strangers?
