The University of North Texas Health Science Center built a flourishing business using hundreds of unclaimed corpses. It suspended the program after NBC News exposed failures to treat the dead and their families with respect.

Long before his bleak final years, when he struggled with mental illness and lived mostly on the streets, Victor Carl Honey joined the Army, serving honorably for nearly a decade. And so, when his heart gave out and he died alone 30 years later, he was entitled to a burial with military honors.

Instead, without his consent or his family’s knowledge, the Dallas County Medical Examiner’s Office gave his body to a state medical school, where it was frozen, cut into pieces and leased out across the country.

A Swedish medical device maker paid $341 for access to Honey’s severed right leg to train clinicians to harvest veins using its surgical tool. A medical education company spent $900 to send his torso to Pittsburgh so trainees could practice implanting a spine stimulator. And the U.S. Army paid $210 to use a pair of bones from his skull to educate military medical personnel at a hospital near San Antonio.

In the name of scientific advancement, clinical education and fiscal expediency, the bodies of the destitute in the Dallas-Fort Worth region have been routinely collected from hospital beds, nursing homes and homeless encampments and used for training or research without their consent — and often without the approval of any survivors, an NBC News investigation found.
