A former Pennsylvania state trooper and private investigator dedicated over a decade to investigating the suspicious death of Philadelphia teacher Ellen Greenberg. He is now urging President Donald Trump’s Justice Department to initiate a corruption investigation in Philadelphia. His criticism extends to Gov. Josh Shapiro for his role in the controversial case.
Recent developments include the forensic pathologist, who performed the autopsy, retracting his initial conclusion that Greenberg’s death, marked by 20 stab wounds, was a suicide.
A significant portion of the stab wounds were found on her back, with one believed to have been inflicted post-mortem. Dr. Marlon Osbourne, who used to work at the Philadelphia Medical Examiner’s Office and currently resides in Florida, first classified the death as a homicide. However, days later, he altered the ruling to suicide following a private meeting with the police. Records of this meeting have not been disclosed, with Greenberg’s parents’ attorney stating that there is no documentation of the police participants or the discussions that took place.
That meeting alone is enough for a federal corruption probe, according to Tom Brennan, the family’s private investigator for nearly a decade and a former Pennsylvania state trooper.
Days later, the City of Philadelphia settled a lawsuit with Greenberg’s parents, Dr. Josh and Sandee Greenberg, that accused local officials and the medical examiner’s office, including Osbourne, of participating in a “concealed conspiracy for the purpose of disguising Ellen’s homicide as a suicide,” according to legal documents.
Brennan is calling for a federal probe into the investigation and city officials by President Donald Trump’s new Justice Department.

“You have people who are actually trying to hide a homicide,” he told Fox News Digital. “Don’t you think the federal government would be interested in the corruption?
“I hope, and I pray that Trump appoints a Republican U.S. attorney in Philadelphia.”
Shapiro’s office did not immediately respond to a request for comment.
