Survivor: Kaoh Rong

Debbie Wanner's guilty plea: 48 months' probation, $147, no prison

Debbie Wanner pleaded guilty on 30 July 2011 in a federal case over falsified laboratory test results and was sentenced on 18 November 2013 to 48 months of probation and $147 in restitution. She served no prison time. She was Blue Marsh Laboratories' lab manager, not its owner.

Court record The plea date, sentencing date, probation term and restitution figure come from the EPA's official summary of the prosecution. The description of the conduct comes from the U.S. Attorney's 2012 press release for the Eastern District of Pennsylvania. Where widely copied entertainment reporting conflicts with those two records, the agency record governs.

What the sentence actually was

Debbie Ann Wanner pleaded guilty on 30 July 2011. Sentencing came more than two years later, on 18 November 2013, and the terms were 48 months of probation and $147 in restitution. The EPA's summary of the prosecution, which lists every defendant in the case and every disposition, records no term of incarceration for her.

That $147 figure is not a typo. It is the restitution amount the record carries for Wanner, and it sits next to a separate joint restitution order of $14,114.50 against the company and its owner. The two numbers are often collapsed into one another in retellings, which is how a four-figure sum ends up attached to the wrong person.

She managed the lab. Someone else owned it

Wanner's title was lab manager. Blue Marsh Laboratories, Inc. of Douglassville, Pennsylvania was owned by Michael J. McKenna, who was also its president and laboratory director. He and the company pleaded guilty in June 2012 and were sentenced on 10 September 2012. McKenna received nine months of incarceration followed by 37 months of probation. The company was placed on probation, and the two were ordered to share $14,114.50 in restitution.

This distinction does most of the work on this page. Summaries that describe Wanner as the person who ran the lab, or that borrow McKenna's prison sentence and place it on her, are describing a different defendant's case.

What the falsified reports concerned

Blue Marsh was in the business of analytical testing of environmental water and wastewater samples. The U.S. Attorney's office for the Eastern District of Pennsylvania described a scheme in which test reports were prepared and mailed to customers falsely stating that proper EPA methods had been followed.

Two examples were named in that release. Between September and October 2005 the lab sent false test results for Hurricane Katrina flood water samples that the EPA required to be tested for pollutants including cyanide and the herbicides MCPA and MCPP. Between approximately July and September 2007 it sent false results for FDA-required pesticide testing of fruit imported from South America. The case was investigated by the EPA Criminal Investigation Division, the FDA Office of Criminal Investigations and the Defense Criminal Investigative Service.

Where the version that circulates goes wrong

The account most fans have read traces back to a TMZ story published on 26 February 2016, while Wanner was on air in Survivor: Kaoh Rong. That story said she pleaded guilty to three counts and was placed on one year of probation, and it framed her as a chemist at a lab taking on clients it could not properly serve.

The official prosecution summary gives 48 months of probation, not one year. It also puts her at the lab as its manager, under an owner who was separately prosecuted and separately sentenced. Where an entertainment outlet and an EPA prosecution record disagree on a sentence, the prosecution record is the one to use.

What this page does not say

Wanner did not go to prison for this case, and she did not own Blue Marsh Laboratories. No charge or finding in the record attributes harm to any identified person, and this page makes no such claim. What the record establishes is a guilty plea to falsified laboratory reporting and a probationary sentence.

No CBS statement, sanction or public comment about the case has been located, and no source shows what the network knew or when. That silence is not evidence in either direction, and it should not be read as one.
