Charges may begin in JDR Court if Alexis is a minor. If the case goes forward, as a murder if that is what happens, it will eventually go to Circuit. It may bypass General District at that stage. Right now, it is just an abduction charge, so he will get a Court appointed attorney, assuming he cannot hire an attorney, and things will proceed as an abduction.
Of course, more will be going on, and if Alexis is found, that will depend on how she is found. Alive or not alive. If she is not found for some time, it may go to a Grand Jury to see if murder charges can be brought without finding her.
If found alive, it may stay in JDR as an abduction and any type of assault.
