My sister got caught stealing at walmart tonight?

My sister who is 19 was with her friend who is 18, got caught stealing two shirts and a bra. She said when she was heading out the doors, the security asked for the stuff back. So I guess they were taken into a room and searched. Then the police were called. She has a paper from walmart that says she was caught and stuff. And a yellow paper from the sheriffs department. It says she's issued a court date and it gives a date but no time. Also, this is her first crime ever. What's going to happen?
