Authorities say the wife of an imprisoned former Greek defense minister has escaped from a psychiatric hospital, where she was serving her sentence on the same corruption charges as her husband.

Vicky Stamati, wife of former Socialist Party stalwart Akis Tsochatzopoulos, was found missing early Thursday from her guarded cell in the Dromokaitio state psychiatric institution.

Stamati was initially imprisoned in 2012 and was convicted in 2013 along with her husband, step-daughter and others in a military procurement corruption case against Tsochatzopoulos.

Stamati was deemed to have known about bribes her husband accepted. She was sentenced to 12 years for money laundering and accepting illegal funds.

In poor health, she underwent a mastectomy after the trial while imprisoned, and was transferred to the psychiatric hospital after suffering a breakdown.
