Call Sprint and ask them if they can use your phone's GPS to locate it. The police might be able to use that information to track down the thieves. Don't go after them yourself! Sounds like a bunch of crackheads to me and they can be dangerous. You should contact the detectives like the police dept. said, and ask them what they think of your idea to have Sprint GPS locate the phone. Act fast, before the battery dies or they won't be able to find it!
