OREGON CITY, Ore. -- Demolition crews using heavy equipment tore into Ward Weavers' single-story home, two weeks after the bodies of two missing teenage girls were found in the back yard.

Sawtooth Roofing, an Oregon City company that donated its work for the project, said the building materials will be recycled after the house is completely demolished on Tuesday.

The FBI said it has collected all the evidence it needs from the house.

"I think demolishing the house, and changing the view and perception of this property as people drive by it is the best thing to do," said property owner Steven Hopkins.

Investigators discovered the remains of 12-year-old Ashley Pond and 13-year-old Miranda Gaddis in a shed and under a concrete pad on the property. They are seeking an indictment against Weaver.
