Next the crime lab people would never ( never) actually question the witnesses, they would merely turn reports over to the police who would question the suspects.
And no they don't have two or three days or weeks to work on just one case. For example they may have 10 cases or more a day to process, they just move from one case to another.
And in many cases they will never know what the outcome of the case was.
