called left no message

received call from this number. No one on other end. Disconnected after a minute.

Someone from this number just called my cell phone. Looked the number up online, belongs to Todd Lee. I tried calling back, got a message that the number I was trying to reach was disconected or no longer in service. Hmmmm, how can a disconected number call me?

received a call from this number today and the caller said he was from the wyoming michigan police department, we had a conversation and then the call ended. i tried to call him back and the number was disconnected. our area code is 616, how can this be a number from a local policeman? and how are they using airtime if the number doesn't exist?
