Great Wolf Lodge family massacre blew up during ‘uncommon’ three-week stay at pricey resort, officials say

Disturbing details paint a graphic picture of how a loving father and his 3-year-old son were stabbed to death inside a popular family resort during the family's multi-week extended stay.

Investigators say Metallica Rose Harrison, 27, used "butcher knives" when she allegedly stabbed her husband, Charles "Chaz" Harrison, 36, and the couple's 3-year-old son.

It happened at the Great Wolf Lodge in Pennsylvania's Pocono region on Monday. The family is from the small rural town of Towanda, Pennsylvania.
