Nothing has silenced Mary Weiss' outrage. She was devastated when her son Dan Markingson committed suicide while enrolled in a psychiatric drug trial at the University of Minnesota in 2004.
"That's how I feel, like they killed him," she said.
She pleaded with doctors to remove him from the study because she was afraid he was in danger of killing himself. He died a horrific death, nearly decapitating himself with a box cutter.
Weiss has spent the past decade accusing the research doctors of misconduct and the University of covering up the abuse. Vindication finally came a few weeks ago in the form of a report from the legislative auditor, which was triggered by a Fox 9 investigation.

Among the findings, Dan was "extraordinarily vulnerable" when his U of M psychiatrist recruited him into a drug study the same doctor was running. There was little evidence researchers followed up on Weiss' concerns her son was suicidal.
