Three of the four Baltimore Police officers still awaiting trial in the arrest and death of Freddie Gray have filed fresh motions asking that their cases be dismissed based on alleged "defects" in the prosecution, according to court records.

Those defects, the officers' attorneys have argued, relate to two recent disclosures — one by a Baltimore sheriff's major, who said he agreed with prosecutors to sign off on the officers' charges without personal knowledge of their foundation; and another by a police detective, who said prosecutors prompted her to provide misleading testimony to the grand jury that indicted the officers, the Baltimore Sun reports.

Attorneys for both Officer Garrett Miller and Sgt. Alicia White argued in nearly identical motions Monday that the disclosures show prosecutors violated the officers' constitutional right to due process, and that the charges against them should therefore be dismissed.

Attorneys for Lt. Brian Rice, the next officer scheduled to stand trial, starting with a motions hearing July 5, also filed a motion requesting dismissal based on prosecutorial defects, though that filing was not immediately available on Tuesday.
