Workers injured in roof collapse

Four people have been injured after a roof collapse.

The four were setting trusses on a new county road garage in Phelps in Pike County when the accident happened.

They were about 3/4 of the way done when one began to shift.

It fell causing the others to collapse in a domino fashion into the structure.

The walls of the building are still standing.

Crews are investigating what caused the first truss to fall.

Two workers were flown to a Tennessee hospital, two others were taken to the Pikeville Medical Center.
