There are at least six known defendant lobbies in the Los Angeles District Court used to house defendants and their defense teams. They are used before and after trials, as well as during recesses, to discuss the trial and to prepare the defense's case. Defendant lobbies are soundproofed to prevent people from overhearing the defense teams inside. Prosecutor's lobbies also exist but have only been mentioned once. Defendant Lobbies 1 and 2 are especially notable for being involved in two incidents, one a double murder occurring in 2012 and the other being Zak Gramarye's disappearance in 2019.
