My question involves criminal law for the state of: CA. My 19 year old daughter was caught shoplifting a $15 shirt from Macy's where she was employed she was not working at the time, they called the police when the police arrived they asked if her phone worked she stated it did but the battery was dead the store manager then took her phone without her permission charged it and with the police proceeded to search through her calls and text messages. She has never been in trouble before and was 100% compliant. Did they have the right to do so without her permission if she already returned the property. Doesn't the search and seizure of a cell phone require a warrant?
