The manhunt continued Wednesday for murderer Danelo Cavalcante, who escaped from a Pennsylvania prison last week by thwarting newly installed razor wire put in place after another inmate briefly broke out a few months ago, authorities said at a Wednesday news conference.

Cavalcante, 34, who was spotted again in the area Tuesday by a resident, got free from Chester County Prison last Thursday by “crab walking” between two walls, pushing his way through razor wire, running across a roof, scaling another fence, and getting through more razor wire, Chester County Prison Acting Warden Howard Holland told reporters.

Surveillance video from the prison shows the inmate in the exercise yard looking through a window in a door then placing his hands on one wall and his feet on another. He shimmies up the opening and out of view.
