Wheeler was connected to Colm Connelly - Delaware prosecutor with good reputation. Connelly was Wheeler's attorney. Biden declined to endorse him for a judge position, but Trump has since made him a judge. Wheeler was last seen exiting the Nemours office building where Connelly's law offices were. Many links now defunct but some good info here:

Quote from AP article: "Attorney General Beau Biden's office, along with police investigators, have sought to keep information about the case from the public. Biden's office asked a judge to seal a search warrant for Wheeler's home, and three search warrants for Wheeler's cell phone and his 1993 Oldsmobile were sealed at the request of Newark police."
Wheeler was also Secy of the Air Force during the Minot-Barksdale incident in 2007.
