The court will hear the dispute between Ellen Greenberg's parents over the death of their daughter in 2011

In 2011, 27-year-old Philadelphia teacher Ellen Greenberg was found dead with more than 20 stab wounds. Although authorities initially ruled her death a murder, the verdict was eventually changed to suicide. Her parents were shocked, as they had long been convinced that Ellen had been murdered.

As Fox News and CBS News report, the Pennsylvania Supreme Court has now agreed to hear Ellen's parents' arguments regarding the cause of death.

Ellen's parents, Joshua Greenberg and Sandee Greenberg, have long been convinced that Ellen died by murder and that the investigation was mishandled. They have been fighting for years to have suicide removed from Ellen's death certificate. Although they have lost legal battles on the matter in the past, they may now have a chance to have the verdict officially reviewed.

“She [judges] have been blatant in saying that the investigation by the police, the coroner and the district attorney was flawed,” Joshua told CBS News in 2023.

According to CBS News, the arguments presented to the Pennsylvania Supreme Court will determine whether “executors and administrators of estates” can challenge a coroner's findings on a death certificate.

“We couldn't be happier. When we don't use the word 'justice,' we use the words 'undecided' or 'murder,' because we believe it was murder,” Joshua recently told CBS about the decision. “Ellen was brutally murdered.”

In early 2011, Greenberg's fiancé, Sam Goldberg, returned to their shared Philadelphia apartment but told investigators he could not enter the apartment because the swing lock on the apartment was activated, blocking his access. He eventually forced his way in and found Greenberg dead in the kitchen. She had suffered more than 20 stab wounds and a 10-inch knife was still embedded in her chest at the time of discovery, according to the investigative report, which was previously reviewed by PEOPLE. She had stab wounds to her chest, abdomen, head and neck, as well as a laceration on her scalp.

Her manner of death was changed from murder to suicide after investigators said they only found Greenberg's DNA on the knife and clothing, PEOPLE previously reported. They also claimed there were no signs of foul play.

However, Joshua and Sandee's attorney, Joe Podraza, claimed to Fox News that the knife's fingerprints were never found and that there were indeed signs of a struggle in the apartment. The network also reports, citing unspecified court documents, that the crime scene was cleaned before investigators arrived to investigate.
