Laura Pettler & Associates
THE #1 VICTIM-CENTERED SCIENTIFIC DEATH INVESTIGATIONS FIRM IN THE WORLD

Casework & Forensic Services

Grounded by law. Guided by ethics.

For law enforcement, prosecutors, defense counsel, wrongful death attorneys, and families

We strive to be accurate, thorough, objective, and ethical in everything we do. None of these are about “us:” not the cops, not the lawyers, not the crime lab, or the witnesses. Cases are about the victims. Cases are about the defendants. Everyone’s lives and families should be treated equally and respectfully. We are not judges. We are not jurors. They are the only ones who truly weigh evidence and determine guilt or innocence.

LPA’s scientific death investigation methods minimize investigator bias and maximize probability for solvability and clearance.

Bring your case to LPA. Our online case management system keeps you informed about work on your case, monthly progress reports keep you up to date, and we always respect your budget.


LPA helps you prepare for the battlefield.

What is Scientific Death Investigation?

People ask us all the time, "how do you guys solve so many cases?" The answer is not as complicated as you might think. Most of the time, cases come into LPA having many or nearly all the pieces they need to move forward, but the pieces are not in the right order and the pieces have not been analyzed. Most often the investigations have been suspect-centered, which has caused the investigation to stall and go cold.

Most cold cases are not difficult to solve. Most hot cases are not difficult to solve. Where the problem comes in for investigators is not having the resources and skill set they need to solve the particular type of homicide they're dealing with.

If you have a specific problem with your aortic valve, you'd want to find the best of the best cardiac surgeon who specializes in aortic valve disorders instead of a general cardiac surgeon and you definitely wouldn't want to have your Primary Care Physician handle it. Detectives are generalists, not experts. They are like your Primary Care Physicians. When you have a specific illness or problem, they send you to a specialist. LPA is the specialist you come to for domestic violence homicides, staged homicides both hot and cold. You wouldn't want to come here for your hot and cold gang homicides, organized crime homicide, sexual serial killer homicides, and the like.

WE ARE LASER-FOCUSED IN A SPECIFIC SPECIALTY AND WE ARE THE BEST IN THE WORLD AT IT.

LPA is victim-centered.

NOT SUSPECT-CENTERED. LPA investigates deaths using a scientific system called Pettler's Victim-Centered Death Investigation Methodology (VDCIM). VCDIM focuses on the victim in a death investigation, murder case, or missing person case. VCDIM is a six stage process that keeps the investigation organized, prevents steps from being missed, has built in safeties to ensure every piece of data is analyzed, and categorizes data so the investigation is constantly moving forward. 


Before you hire any investigator: Authentic v. “Fakes”

There are legitimate reasons why private investigators and industry professionals often get a bad rap. There are also genuine reasons why law enforcement is often leery of working with private investigators. Before you hire a private investigator, death investigation firm, or consultation agency, consider this:

  • True industry professionals who are highly educated, extremely well-trained, and come with years of successful experience don’t have to talk to establish credibility

  • “Fakes” don’t have the chops, so they talk, talk, talk, trying to prove themselves in the industry

  • True industry professionals don’t seek fame and followers

  • “Fakes” will crawl over the backs of their clients and cases to gain fame and followers

  • True industry professionals who’ve spent years in death investigation respect boundaries

  • “Fakes” know no boundaries and will do anything to achieve their goals

  • True industry professionals know that premature publicity can jeopardize the integrity of a case, create false leads, waste valuable fiscal and human resources, cause changes of venue due to pretrial publicity, cause a defendant not to get a fair trial, and the list goes on

  • “Fakes” don’t care about any of the above because it doesn’t align with their goals

  • True industry professionals don’t care about glory, credit, or accolades

  • “Fakes” will take credit for cases they never investigated or worse take credit for solved cases they didn’t solve

  • True industry professionals work with the media to build case awareness appropriately without jeopardizing the case

  • “Fakes” will try to sell you on running straight to the media with your case under the guise that they have the your best interest at heart

  • True industry professionals demonstrate their true intention by supporting law enforcement; they offer partnership to bring in support and resources towards justice for victims and answers for families

  • “Fakes” don’t offer solutions, they only throw stones without ever having done the job themselves
