A prescription bag was a piece of evidence in Phoenix Wright's investigation into the death of Jack Shipley.
The bag was one of the items confiscated by the police while they searched the home of Sasha Buckler after she was arrested on suspicion of murdering Shipley. It was medicine for a heart condition. Detective Bobby Fulbright later gave it to Wright, who passed it onto her at the detention center. Through this, Wright was able to learn more about Buckler's mentor, Azura Summers, who had suffered from a similar condition.
