The couple kidnapped from their Monos Island home over the weekend, Derek “Stones” Tardieu, 70, and his wife Claribel, 47, remained in the hands of their abductors up to this afternoon, even as police continued investigations into their disappearance.

GUN TO HIS HEAD: Derek Tardieu and his wife, Claribel, seen here in a clip from a disturbing video used by the kidnappers to demand a ransom of US$2.5 million for their safe release. The two red circles above have been drawn to show a rifle pointed at Derek’s head as well as a grenade in front of him.

The Tardieus were snatched from their residence on Saturday night. Hours later, relatives received a disturbing video showing the couple standing before bushes in daylight, with an assault rifle pointed at Derek’s head and a hand grenade held close to his face. Derek was ordered to plead for assistance and demand a ransom of US$2.5 million.
