It's that time of year when cemetery guards go on alert for signs of an old, ghoulish and persistent crime: grave robberies.
There's no definitive evidence that thefts rise around Halloween, but officials take no chances.
Guards keep a closer eye on their rounds, and security workers are extra vigilant when monitoring motion sensors and cameras.
It's usually pranksters or thieves. Occasionally, it's occultists seeking ritual objects, like in Philadelphia in June when two teens were arrested on suspicion of stealing remains from a crypt.
Bob Fells, general counsel for the International Cemetery Cremation and Funeral Association, says thieves have also started going after bronze artifacts as the price of the metal has skyrocketed.
