Convicted murderer Molly Martens could face an extra three years in jail for allegedly breaking prison rules.
The 34-year-old former au pair is serving a minimum sentence of 20 years for killing her Irish husband Jason Corbett at their home in North Carolina.
Martens now faces a three-year extension after she was cited last month for "unauthorised leave" - meaning she left a supervised area without permission or did not report to one as required.
