Hi there and welcome
As long as she has not reset it yet you can.
Click on my link below and sign in with the same Gmail account you used on the Tablet
If its not wiped, you can see its location and wipe it from there.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
