and joins us with more. >> reporter: the court hearing just adjourned a little while ago. all of the testimony is over. the judge now has to decide what kind of charges the prosecution gets to prove to the jury. was it second-degree murder, was it manslaughter or was francisco lopez sanchez simply a bad shot. the fourth day of hearings started with testimony from erin carpenter, a tourist staying at a hotel opposite pier 14. she took cell phone pictures from her hotel window of francisco lopez sanchez walking away briskly after she heard gunshots. carpenter said she was suspicious of him because he was the only person walking away from kate steinle, now lying on the grounld, when everyone else was going toward her. she gave the images to police. prosecutor diana garcia also called three officers who responded to the scene. officer andrew bryant was the one who arrested sanchez. he's one of the officers in the cell phone video of the arrest. during the preliminary hearings, prosecutor diana garcia called a ballistics expert who showed the gun similar to this one that sanchez is accused of firing. public defender matt gonzalez called only one witness, but he was crucial to his defense, that the gun went off accidentally. form sfpd crime lab director jim norris said last week that he supported gonzalez' theory that it was an accidental discharge. that based on earlier testimony from an investigator that the bullet struck the peer walkway first, then ricocheted, hitting steinle in the back. >> i believe that while the defendant was aware that something had happened with this thing that he was holding, i actually don't believe he was aware that someone was shot on the pier. >> reporter: so the preliminary hearing continues tomorrow morning and the judge is
