7. Sаl is аn evidence cоllectiоn techniciаn fоr the local police department. He recently was called to the scene of a murder that occurred at 9 in the morning. Sal processed the scene until about 3 p.m., placing numerous items of evidence in bags before placing them in the locked trunk of his car. Sal’s son had a baseball game that afternoon at 5 p.m. and Sal drove directly from the crime scene to the baseball field. Sal made sure the car and trunk were locked before walking to the stands to watch his son play. During the game, someone broke into Sal’s car and rummaged through the bags in the trunk. The person removed a gun from one of the bags that Sal recovered at the scene but dropped the gun a short distance from the car. Sal had taken a picture of the gun at the scene and it appeared the gun that was dropped near the car was the gun recovered at the crime scene. At the murder trial, the prosecution sought to introduce the gun into evidence, the defense objected, and the judge sustained the defense objection. What is the most likely basis for the judge’s decision?
