So I was just reading info on the FBI. I'm not sure if I'm reading this right or fully understand but FBI doesn't get involved in cases like this unless if its believed that a child was taken across state lines or there has been a kidnapping?
FBI Jurisdiction in Child Kidnappings
In the public eyeand even in some state and local law enforcement circlesthere are common misconceptions about when the FBI can get involved in child kidnappings. That there has to be evidence a victim has been taken across state lines. Or that a ransom demand has to be made. Or that 24 hours must pass.
All are false.
Whether the case ends up being investigated and prosecuted at the local level or at the federal level, the Bureau will always leverage our investigative resources and technical assets to work hand in hand with state and local law enforcement agencies on cases involving the mysterious disappearance of a child. Our role is to help investigate the disappearance, recover the child, and apprehend the person or persons responsible.
And that role begins as soon as were notified

Our field offices respond to cases involving the mysterious disappearance of a child whenever and however they come to our attention. All reports of circumstances indicating that a minor has or possibly has been abducted are afforded an immediate preliminary inquiry.
In this initial inquiry, we evaluate all evidence, circumstances, and information to determine if an investigation is warranted under federal law. (For instance, it is a federal violation for a person to travel between states to engage in any sexual act with a person under 18.) If a case is warranted, we will immediately open an investigation in partnership with state and local authorities.
During 2012 alone, law enforcement entered 797,400 children as missing into the FBIs National Crime Information Center database. Although the majority of these children were temporarily missing and not abducted, we are committed to assisting law enforcement in investigating cases where there is appropriate jurisdiction.

Law Enforcement Assistance
This is the arm of the FBI that has been popularized by television and movies. FBI teams are sent to local law enforcement agencies to help handle investigations. There are times when the FBI agents are there to support the local police, and there are times when the FBI agents are there is take over an investigation the local police cannot handle.
The FBI has one of the most sophisticated crime labs in the world, and they can send evidence for analysis to Quantico much more quickly than a local police agency can get the same evidence tested. The FBI also supports state investigative agencies. Every state has its own version of the FBI, and that state agency often turns to the FBI for assistance.
Finally, local law enforcement agencies call on the FBI immediately when they know they have a case that is too big for them. The local police are wise to contact the FBI when an investigation has just begun. The involvement of the FBI often forces thieves to make rash decisions, and the extra manpower can help to solve crimes quickly.
