She was crying and said I need help. I don't know where I am. I'm lost, please help me. Reporter: You knew something was wrong. Right. I knew she was scared and wherever she left from she left quickly because she had shoes that were too big for her, black leggings and a sweatshirt.

Reporter: Incredibly, Jayme was able it to give the name of the person who kidnapped her and gave a description of the vehicle that led to his arrest. One of my patrol sergeants happened to find a vehicle that matched the description that Jayme gave my detective and pulled the suspect over and took him into custody at that time. Reporter: Jay Thomas expected to be charged with two counts of homicide and one count of kidnapping. In cases like this we often need a big break, and it was Jay me herself who gave us that break.

The call was given that night from the residence on a cell phone, but no contact was made with somebody that was on the other line. There was no one communicating with our dispatcher. Reporter: Police arrived within minutes of the call. Jayme's dad James lay dying. Her mother Denise already dead. Neighbors say they heard gunshots. I heard one shot and the second shot was louder yet. Reporter: Authorities found bullet casings but no weapon and no Jayme. An amber alert was issued nationwide and local authorities enlisted the FBI to help them. Our goal to bring Jayme home. She is the sweetest little girl. She wouldn't hurt a soul.

We believe the suspect was out looking for her when law enforcement made contact with her. Reporter: There was no social media contacts with her but that he specifically targeted the young girl. Nothing in this case shows the suspect knew anyone at the Closs home.
