✔ 最佳答案
I don't know how to track a cell phone ping. But I do have other suggestions. I suggest notifying the local police, if you haven't already. The parents need to call the Detective on the case on a daily basis and ask for an update. Call the local newspapers, local TV news stations etc.., and see if they will air something for you. Contact churches, women support groups and any local agencies you can to help you in searches, put out posters etc..,
The more attention you can get on the case, the better. Also you want the missing person to know that you did everything in your power to locate her
Good Luck!
