Reasonable Doubt is examining the 2008 murder of Mary Elizabeth “Liz” Hermann by Justin Lunsford in Cave Creek, Arizona.
Hermann is sometimes referred to in reports and documents as Mary Polger, which had been her husband’s surname; however, the pair reportedly separated a short time before her murder.
Lunsford was convicted of Hermann’s murder in 2011, but he has continuously maintained his innocence, and his family and friends have insisted that he is the victim of a miscarriage of justice. The team at Reasonable Doubt has decided there is enough “doubt” in the conviction for them to investigate the case.
On July 8, 2008, Cave Creek firefighters discovered the gruesome remains of Hermann in a house that had been badly damaged in a blaze. She had been stabbed more than 50 times, and her throat had been slit with such ferocity that she was almost decapitated. Her body was naked, and she had stab wounds on her head, neck, abdomen, back, and groin.
Hermann’s cat and dog had also been stabbed to death, and her truck had been driven to another location and deliberately set on fire. The investigators concluded that the fires at the house and the truck had been started deliberately with an accelerant such as gasoline.
Justin Lunsford was the number one suspect in Mary Hermann murder
The cops soon learned that Lunsford was one of the last people to have seen her alive. The previous evening they were spotted leaving a Cave Creek bar, and they were known to have then gone to purchase drugs together.
An eyewitness came forward to say they had seen a man in a green truck leaving Hermann’s truck just as the vehicle caught fire. Lunsford’s truck matched the description of the one spotted by the witness and the cops found a can of gasoline in the vehicle during a search.

The friend also claimed that Lunsford had set the two fires, but had done so to destroy the evidence that would frame him.
The cops and the prosecutors weren’t buying this story, so they decided to press ahead with charging Lunsford with murder.
In the spring of 2011, Lunsford was expected to go on trial for first-degree murder, arson of an occupied structure, burglary, arson of property, two counts of animal cruelty. If a jury had found him guilty, he would have likely faced the death penalty.
However, shortly before the trial, Lunsford agreed to enter a guilty plea. He pleaded guilty to second-degree murder and one count of arson of an occupied structure, which led to him receiving a reduced sentence of 23 years.

How does a person get in touch with the producers or the persons that make the decisions on what cases to review, I know of one that really needs to be reviewed, it was an 16year old cold case and when a certain former detective in louisiana opened it back up it was ruined by him making it a spectacle on his podcast, when the case has been tried it was a guilty verdict from the start because of that with no substantial evidence to support the verdict, i wouldn’t be surprised if a few payoff went along with some of the investigations
Liz was my friend. I still grieve for her short life and her family that lost a beautiful soul.
