Cant delete user folder or media device

I made my girlfriend an account on my new laptop but she didnt want it anymore so i removed it, but i noticed that when i go into my users folder her folder is still there and it wont let me remove it. Also under network it still has her email there as a device and i cant figure out how to remove that either, and if i right click any folder on my computer and go under the share with option it still shows her email there also. anyone know a solution to this?
