A 2008 mug shot of Tammy Feldbaum after she was charged with spitting on a state trooper and threatening court officials involved in her homicide case.

A Westmoreland County transgender woman who spent more than a decade in prison for the castration and overdose death of her husband in 2001 in Butler County and threatening court officials was found dead in her home last week, according to a news report.

Tammy Felbaum, 65, was found dead Wednesday, Oct. 11 in her Seward home by police who conducted a welfare check due to an accumulation of mail, according to the report, which said the coroner’s office determined she died of natural causes.

In December 2001, Felbaum was sentenced to serve five and a half to 11 years in state prison after she was convicted of involuntary manslaughter, aggravated assault, reckless endangerment and unauthorized practice of medicine in the death of her sixth husband, James Felbaum, who was 40, according to Butler Eagle archived articles.

Suspecting her husband was cheating on her, she castrated him in February 2001 and stitched a catheter into his body in a filthy mobile home they shared in Marion Township. The home contained a makeshift operating room with surgical equipment.

He choked to death on his vomit on Feb. 25 after injecting himself with oxycodone due to the pain from the crude operation.

During the investigation into the death, police found the mobile home was full of live and dead animals, feces and blood-soaked cloths.

In court, Felbaum claimed her husband performed the operation on himself as a sign of devotion to her, and he was then overcome by the drugs.

In 2008, she pleaded guilty to aggravated assault by a prisoner and three counts of terroristic threats for threatening court officials involved in the homicide case and spitting on a state trooper who was taking her to her arraignment on the charges. She was sentenced to serve 21 to 60 months in prison.

The charges stem from letters Felbaum mailed in 2006 from her cell in SCI Cambridge Springs, a women's prison in Crawford County, threatening to kill William Fullerton, the assistant district attorney who prosecuted her homicide case. Fullerton is now a district judge.

Authorities said Felbaum wrote similar letters to Judge William Shaffer, who convicted Felbaum following a nonjury trial, and Timothy McCune, who was district attorney at the time of Felbaum's trial. Shaffer is now a senior judge and McCune is a Common Pleas Court judge.

In addition, Felbaum was given probation sentences after pleading guilty to theft in 2021 and disorderly conduct in 2017 in Westmoreland County. She was sentenced to probation after pleading guilty to driving under the influence of a controlled substance in 2018 in Allegheny County.
