7. The Mysterious Death of Ellen Greenberg Part 2
Red String Theory
12/15/24 • 28 min
The case we're diving into today dates back to 2011, but the fight to determine the true cause of death is still ongoing in the courts. This is Part 1 of the perplexing and heartbreaking case of Ellen Greenberg.
Ellen was a 27-year-old first-grade teacher found dead in her apartment on a snowy evening in Philadelphia, Pennsylvania, on January 26, 2011. She had been stabbed 20 times, and her death was shockingly ruled a suicide—despite the violent nature of her injuries. This ruling sparked a 13-year battle for her family, who have relentlessly fought to have her cause of death reclassified as a homicide.
Content Warning: This episode discusses sensitive topics like suicide and domestic abuse, which may be upsetting to some listeners.
