Police said a cemetery worker and two people visitors heard a woman’s voice from inside the 49-year-old cancer patient’s grave on Thursday.

The sounds were reportedly heard by the passers-by shortly after the last relatives of the deceased had left her funeral in the northern town of Peraia.

They are believed to have dug up the grave to try to save her, but by the time they got her out of the ground she had suffocated inside the coffin, according to Greek media.
