A YKHC press release says the locks on display cases were picked. YKHC Risk Management Director Linda Weisweaver says none of the displays were damaged and it appears the burglar tried to hide the theft.“All the pieces that they removed were really smaller. The biggest one was probably a foot and a half tall tusk, a walrus tusk that had been carved. The majority of them would fit inside someone’s coat or jacket,” said Weisweaver.Weisweaver says some of the items were taken apart, with only the ivory portion missing. The items taken are estimated to be worth over $11,000.YKHC is offering a $1,000 reward for information leading to the arrest of the thief or the safe return of the stolen art. In the meantime, they’ve doubled their security detail.Officials ask anyone with information to contact the Bethel Police Department.For images and descriptions of the stolen items click here.
