Boston Public Radio looks at an Oklahoma City crime lab worker so infamous her exploits were made into an episode of “Law & Order.”

A star employee at a crime lab takes on a huge caseload, gives testimony in important trials, and gains the trust of colleagues before it is revealed that she was tampering with evidence and may have sent innocent people to jail. Sound familiar? In 2001, Oklahoma crime lab had its own rogue scientist, and the results were disastrous.
