Shannon O’Roark Killed Estranged Air Force Husband’s Mistress Veterans Affairs Psychiatrist Dr. Irina Puscariu; Col. Roscoe Griffin Made Affair Official on Facebook (2012)

On January 13, 2012, Shannon O’Roark of Texas drove 250 miles to Missouri to kill her estranged husband’s mistress fourty-six year old Dr. Irina Puscariu. Shannon O’Roark Griffin was an aeronautical engineer who worked for NASA training astronauts until she experienced a seizure that put her on definite sick leave. Shannon’s husband was a Colonel in the Air Force who decided he wasn’t ready to retire. Shannon and Col. Roscoe Griffin had been living separately for quite some time and discussed divorce but it appeared Shannon did not want a divorce after twenty years of marriage. Meanwhile, Col. Griffin lost a fellow service member to suicide and it devastated him. He began seeing Dr. Irina Puscariu, a Veterans Affairs psychiatrist, for help. The professional relationship evolved into a romantic relationship, which is strictly forbidden in the world of psychiatry. Dr. Puscariu put her own career at risk when she chose to date Col. Griffin. Shannon found out thru social media that her husband was seeing Dr. Puscariu when he posted a picture with Irina on Facebook. Col. Griffin also changed his relationship status to “it’s complicated” which to Shannon was rejection, and rejection was the trigger. Col. Roscoe Griffin had no idea what was in store for him when someone is dumped and dangerous.

Shannon may have felt like the post meant the last twenty years were horrible and now I am going to replace you. Shannon asked Col. Griffin to go to a counseling appointment with her one last time in an effort to save the relationship. It would be here she would learn her husband of twenty years loved Dr. Puscariu and wanted to continue to see her. After this counseling session is when Shannon decided to go to Missouri and kill Dr. Puscariu. She wanted to protect what was hers at all costs. She wanted to obliterate Dr. Puscariu from her life so the problem would go away. She drove 250 miles to Irina’ home in Missouri and shot and killed her four times in front of her own mother, the last shot was to her face. Shannon then fled the scene back to Texas and was held in custody until she could be extradited back to Missouri for a murder charge. Shannon plead guilty to second degree murder to avoid a trial. She was sentenced to twenty years for second degree murder and twenty years for armed criminal action. Investigators noted that before this incident Shannon had zero criminal history or violent behavior, she didn’t even have a speeding ticket. But when she got rejected by her husband Col. Roscoe Griffin, it would be jealousy and revenge that would drive her to murder the woman who stole her life.
