Doesn't help your situation but I hope you and all other readers are installing android device manager on their phones right now. 

We didnt have one of those apps preinstalled. We've tried recovery programs, but the phone isnt connected to the internet, so its nigh impossible.

Use one of those "find my phone" apps like Plan B. Her provider may offer a location tool at their website. 

My friend lost a bag with valuables in it (including her phone) near new brighton. The bag is a small, black, knit bag/purse with long straps. Her phone is a Samsung s4 with a white case. Thank you so much to anyone who can help!

Lost bag and phone.
