How to track stolen devices once you retrieve your old Blackberry's phone number?

My iPod nano, Nikon camera, and Blackberry were all stolen from my bag. In just one sweep, she robbed me of my most valuable possessions. This took place at a high school girl's locker room, and I have yet to find the perpetrator since.

After some explaining, the kind people of MetroPCS we're courteous enough to reveal some vital information. The one who stole my things had deactivated the phone and reactivated it with a new number. Now, I won't disclose the phone number or name online, as I fear things will get out of control. I'm only asking for advice on how to get my stuff back from here. I've called, and from listening to the voice I can definitely tell the owner is a female. The phone is listed under a male's name, which means her male family member is cooperating! Great influence, huh?

Here's the twisted part: They reactivated the phone through the automated service MetroPCS provides. This person had to know my birthday and several personal details to get away with this. I could trust this person and remain completely ignorant over what they did to me.

Please help me get my stuff back. My family is very stressed. We don't have money to replace all the lost items and they had to work to earn them. Whoever this is, she doesn't deserve to take from us this way. Especially if she knows me personally.

Any help or advice will be appreciated. Thank you.

Added (1). I already spoke to the police, they refuse to find the GPS location of the phone. However, after communicating with her some more I managed to find the girls Facebook. Where should I go from here?

The only option would be to file a police report
the police can then find the exact GPS position of the phone.

if the police refuse to get involved… (hard to believe), then you can either take her to small claims court, or forget it.

Did you file a police report?

If not, then there's probably nothing else that can be done.

You do not listen well. I never told you to tell the police to find the phone. I said file a police report indicating that your phone was stolen and then let the police worry about it.
