​​Post-Conviction Investigation Requires a Determined, Experienced Investigator

Appellate and Post-Conviction cases frequently involve a much more insightful, rigorous, in-depth analysis of the original case's discovery, the trial and hearing transcripts, previous investigative work, evidentiary review, etc., and if done properly, will inevitably take much longer than the original civil defense or initial criminal defense investigation.

Post-Conviction cases are investigated as cold cases and take time. There is no way around it, especially if the Attorney is filing a Personal Restraint Petition (PRP) with the Court. The aim of the PRP is to locate the "newly discovered evidence" that can help exonerate someone, if possible. This cannot be done, without a meticulous analysis of all facets of the case, prospectively locating and interviewing victims, witnesses, jury members, and in many instances...even the prior defense attorney, defense investigator and/or the prosecutor.


A vital part of our process typically requires a thorough examination of your prior attorneys' and investigators' files. This is essential, because we are working tirelessly to locate the necessary evidence to challenge the initial Court's ruling, which includes the verdict rendered and/or sentence imposed. Investigating a case like this is not a simple undertaking. For this reason, it is imperative that you have a determined, experienced investigator with the expertise necessary to acquire what is needed. Thankfully, Dr. Harrington has developed a distinct skillset that he employs to assist his Client's in coordinating and conducting methodical investigations, throughout the Post-Conviction process.​


Our Commitment.....

Once again, please remember that thorough investigations take time. With many factors, foreseen and unforeseen, impacting the outcome...there is simply no way around it. And, while you may be seeking a rapid resolution of your legal situation, it may not be practical, or even realistic. Trust that the most beneficial remedies often occur, when we have exhausted all other possibilities.

You must also understand that no one can guarantee the result of an investigation. The only promise an investigator can legitimately make is that they will pledge to do everything they are legally able, within reason, to help you favorably resolve your legal matter. Given this, a competent attorney will always be the one to determine the best course of action after thoroughly processing and analyzing the investigative findings. The rule is, your attorney will ultimately determine the optimal legal strategy.

Although Harrington Investigations may be involved in the process of preparing your case for trial, it is solely your attorney's duty to provide competent legal advice...never the investigators.
