Witness credibility investigations are important because lawyers cannot afford to not check out every person in you trial. It's too important. As a Certified Legal Investigator I know how important this information is to you.
Insuring the credibility of every witness involved in your case is absolutely necessary. It's just good due diligence to make certain that there are no surprises when your witness gets up on the stand. I know. I've seen the effects when an opposing party put a witness on the stand that was supposed to be upstanding and above reproach; only to find out that he had a criminal background and outstanding warrants at the time of the trial.
What about the witness that's supposed to be an expert? Do you have the time and ability to verify his/her credentials. Have they testified in court before? Have they ever had their testimony thrown out and now they are going to testify against your client? We can find out for you.
We can check and canvass neighborhoods to find out about past problems with your client or opposing witnesses. We can check former employers to see how their work habits affected their work product. We've even done crime reenactments to demonstrate the 'witness' could not have physically seen what he reported to have seen.
