Not in the Baltimore area. Look for the case to be moved to the state capital area.
Even outside of Baltimore, no judge is going to grant a motion to dismiss this case. Some of the charges against some of the defendants may end up dismissed, but not the whole case. In light of the allegations that the officers violated department policy by placing Gray in the van in handcuffs and ankle restraints but no seatbelt, repeatedly refused Gray's requests for medical attention,* and Gray wound up dead, no judge is going to dismiss this case before it gets to a jury.
* There are some radio communications that indicate that the officers eventually did request an ambulance, but not until the van's final stop, an hour after Gray was taken into custody.
