Murderer escaped US jail by scaling wall and climbing over razor wire

Breakout in Pennsylvania wasn't detected by guards for an hour, officials say, as Danelo Cavalcante eludes manhunt for seventh day

A murderer made a brazen escape from a jail in the Philadelphia suburbs by scaling a wall, climbing over razor wire and jumping from a roof. The breakout was not detected by guards for an hour, authorities said as the killer eluded a widening manhunt for a seventh day.

The timeline and details of Danelo Cavalcante's escape - including that he got out using the same route another prisoner took in May - were released as police flooded a search zone of increasingly worried residents. A tower guard on duty during the breakout was put on leave as part of the escape investigation.
