Without knowing the Apple ID and related password, you can't help her.
If you have those credentials, these are the steps you can perform: If your iPhone, iPad, or iPod touch is lost or stolen,
and/or:--> Use the Find My app to locate a missing device or item,
and/or:--> If Find My is offline or not working
and/or:--> If Find My iPhone or Find My iPad isn't enabled on your missing device
Regards and best of luck.
