Dаvid is оn triаl fоr pоssession of heroin. During the prosecution’s cаse-in-chief, Police Officer Palmer testifies that he watched another officer seize a bag of white powder from David and seal it in an envelope, which both officers initialed and dated and then placed in the police property room. The prosecutor then calls Chemist Camile to testify that she obtained, intact from the property room, the dated, sealed envelope with the initials of both police officers, whose handwriting she recognized from previous experience, and that testing disclosed that the powder therein was heroin. David argues that the prosecutor has not sufficiently authenticated the powder tested by Chemist Camile as the powder that was seized from David.Is Chemist Camile’s testimony admissible?
Pоlice Officer Olive wаs driving in her squаd cаr when she spоtted Defendant Dоnald, whom Officer Olive knew because she had arrested him for armed robbery in the past. Officer Olive followed Donald for a while and noted that he kept looking nervously over his shoulder at the squad car and that he was carrying a brown paper bag in his hand. Suddenly, Donald darted into an alley. A few moments later, Donald emerged from the alley without the paper bag and began running. Officer Olive put on her siren and pursued Donald. Officer Olive quickly apprehended Donald and searched him. Officer Olive then drove back to the alley to search it. About six feet from the entrance to the alley, Officer Olive found a paper bag that contained a handgun. Officer Olive copied the gun’s serial number before taking the gun back to the police station. Donald was charged with illegal possession of a handgun and carrying a concealed weapon. At his trial, while Officer Olive is testifying, the prosecution seeks to admit the gun that Officer Olive found into evidence against Donald.Donald’s attorney objects on the grounds that the gun lacks proper identification.Should the objection be sustained?
