It’s now been one week since 34-year-old Danelo Cavalcante broke out of Chester County Prison, setting off a massive manhunt.
Federal and local agencies have been searching since August 31 for the 34-year-old convicted killer.
During a press conference on Thursday, authorities said there was a possible sighting of Cavalcante just before 12 p.m. in the vicinity of Longwood Gardens.
“A search of that area has been underway for the past few hours and continues at this time,” said Pennsylvania State Police Lt. Col. George Bivens.
Cavalcante was spotted on Longwood Gardens’ trail camera on Monday night. Bivens said the possible sighting on Thursday was not far from this location.
Investigators still believe he is within the search perimeter.
