Wife Kills Husband's Mistress: Shannon O'Roark Griffin Charged With Murdering Irina Puscariu

A former NASA specialist allegedly drove 250 miles to shoot and kill her husband's mistress after he refused to end the extramarital affair.

Police say that Shannon O'Roark Griffin left a marriage counseling session in Kansas on Friday after her husband Roscoe Griffin revealed he was having an affair and refused to break off the romance, The Associated Press says. He told his wife that he wanted to get a divorce, police told The AP.

Later that afternoon, O'Roark Griffin, 52, arrived at the home near Kansas City, Mo. of psychiatrist 46-year-old Irina Puscariu, Griffin's lover, and shot her in the face three times, KDAF says. Puscariu's mother was home and witnessed the shooting, police said according to ABC.

However, it's possible that the affair was already over by the time O'Roark Griffin showed up in Kansas City.

A retired Kansas City police officer who was friends with Puscariu told KCTV that she ended the relationship with Griffin, an Air Force colonel, when she learned he was married.

Officers from the Kansas Highway Patrol caught O'Roark Griffin near Wichita, who admitted that she had two unloaded handguns in the car, WFAA reports.

O'Roark Griffin is being held in jail on $1 million bail for first-degree murder charges.

CORRECTION: An earlier version of this story said that the Griffins' therapy session occurred in Texas. It actually took place in Kansas. We regret the error.
