JonBenet Ramsey and Ellen Greenberg intruder

For more than a decade, the family of a woman stabbed 20 times — including 10 from behind — has battled to have the Philadelphia medical examiner’s ruling that her death was a suicide overturned.

Ellen Greenberg, a 27-year-old teacher, was found covered in bruises and stabbed to death in her apartment during a blizzard more than a decade ago. Despite the blood-soaked crime scene, evidence her body had been moved and stab wounds to the back of her skull, investigators found “no evidence of a struggle in the kitchen area or anywhere else in the apartment.”

Dr. Marlon Osbourne, a former pathologist at the Medical Examiner’s Office in Philadelphia, initially ruled the death a homicide, based on the injuries, then backtracked and revised the manner of death to suicide after conferring with city police, according to a civil lawsuit from Greenberg’s family.

An appeals court heard arguments in a civil lawsuit this week and will decide whether it can move to trial.

Lawyers on both sides of the appeal made their cases before a three-member panel of the Commonwealth court Tuesday, Joe Podraza, an attorney for Greenberg’s parents, told Fox News Digital.

“We are cautiously optimistic that the panel will find the estate of Ellen Greenberg may proceed to trial on her mandamus and declatory actions against the City (of Philadelphia) and Dr. Osbourne so that the manner of her death may be changed from suicide to something else,” he said. “Only then can we begin to secure justice for Ellen.”

He said he expects the panel to reach a decision in the next three to six months.

“[The] judges were well-prepared and versed about the issues,” he said. “The judges also displayed the proper degree of sympathy over Ellen’s death and the terrible circumstances surrounding her death.”

Greenberg’s fiancé Sam Goldberg called police on Jan. 26, 2011, to report coming home to find her dead in the kitchen of their Philadelphia apartment, according to court documents. 

Four key pieces of evidence caused him to doubt Osbourne’s finding of suicide, he said. A wound to the top of her head, the fact that she was found seated upright, but blood had dripped sideways across her face — indicating that she had been moved — a large amount of bruises at different stages of healing, and the fiance’s claim that he broke the locked door down when crime scene photos show the latch still attached to both the door and the frame.

Several forensic pathologists, including Dr. Cyril Wecht, one of the country’s leading experts in the field, reviewed Dr. Osbourne’s findings over the years and found the circumstances “strongly suspicious of homicide.”

“In all my years of experience, and all of the homicides that I’ve done, and suicides, I’ve never seen anything like this,” he told Fox News Digital earlier this year.
