If a suspect you are questioning has no I.D. on them and you suspect that they are lying to you about who they really are, take all their pertinent information (i.e., name, height, weight, D.O.B., etc.) and pretend to run a name check on their bogus information. Wait a few minutes and then tell the suspect that they are wanted in Texas for murder. I guarantee they will now happily tell you who they really are.
