The former Pennsylvania state trooper and private investigator who spent more than a decade digging into the suspicious death of Philadelphia teacher Ellen Greenberg wants President Donald Trump’s Justice Department to launch a corruption probe into Philadelphia as he slammed Gov. Josh Shapiro over his involvement in the controversial case.

The remarks come shortly after the forensic pathologist who conducted the autopsy finally abandoned his highly disputed finding that her death from 20 stab wounds was a suicide.

Half of them came from behind, including one that experts say was likely inflicted after she was already dead. Dr. Marlon Osbourne, a former member of the Philadelphia Medical Examiner’s Office who has since moved to Florida, initially ruled her death a homicide but changed his finding to suicide days later, after a closed-door meeting with police, according to court records. Details about that meeting have never been made public, and the lawyer for Greenberg’s parents said no record of who took part from the police department or what was discussed inside exists.

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.
