i just hope the general meaning of what i was trying to convey came across, even if i did use the wrong wording.
she knew he was felon to begin with. she bought the gun for him. he used the gun in the commission of a criminal act. she had to know he had ill intents for the use of the gun since he couldn't legally buy it himself. that make her an accessory in the conspiracy to commit a felony IMO as well.
