Did a Boulder City psychologist murder his wife, or was it a suicide?
LAS VEGAS (KSNV NEWS3LV) —
It's a question the Clark County Coroner can't even answer.
"Based on a review of additional evidence received from the Henderson Police Department related to the death of Susan Winters, the Clark County Office of Coroner/Medical Examiner has changed the ruling on the manner of Mrs. Winters' death to undetermined," said Clark County Coroner John Fudenberg in a statement.
Fudenberg originally ruled the death of Susan Winters a suicide.
He isn't talking about what that new evidence is, but what killed her remains the same.
Winters died from a lethal combination of painkillers and antifreeze.
The husband of Susan Winters, Dr. Gregory Dennis, has been charged with her murder.
On Jan. 3, 2015, Winters was found dead in her bed inside her Henderson home.
According to Henderson Police, Dennis showed detectives an internet search about anti-freeze. He told them she was suicidal.
By February, the case was closed. The coroner ruled her death a suicide.
Her parents didn't buy their son-in-law's story, so they hired a private investigator.
The investigator's deposition of Dennis revealed a doctor with an expensive drug habit, a stormy marriage and a payout from her life insurance.
Henderson Police reopened the case.
Clark County Coroner John Fudenberg is now backing away from his original ruling of suicide. He changed her manner of death to undetermined.
Michael Pandullo is a criminal defense attorney who is not involved in the case.
"There's still enough doubt, even in the mind of the Coroner, that they can't make the determination whether it's a suicide or a homicide," he explained.
"For prosecutors, looking at that alone, this would be a tougher case for prosecutors, then most murder cases that you see," he continued.
Richard Schonfeld, Dennis lawyer, says the coroner's new ruling begs the question why his client is charged with a crime.
"If they can't make that determination, how is the state going to prove a criminal case beyond a reasonable doubt?" asked Richard Schondfeld.
Schonfeld told News 3 that in the next few days, new evidence would be made public that will describe Winters' mental health history.
He says, for the first time, you will see a new side to this story.
