Annie Dookhan has been ordered to pay $2 million to a man who spent 15 months in prison based on evidence that she falsified. It's the first time Dookhan has been ordered to compensate any of the thousands of defendants convicted on the basis of lab tests that she tampered with as a state chemist. 
Reporter Shawn Musgrave has been following the Dookhan story and its fallout. He discussed this latest chapter with WGBH's All Things Considered host Barbara Howard.
