Who is Danelo Souza Cavalcante?

34-year-old Danelo Cavalcante, was sentenced to life in prison without parole for stabbing 33-year-old Deborah Brandao to death in 2021 while her 7-year-old daughter and 3-year-old son were present. He was awaiting transfer to a state facility when he escaped Chester County Prison just outside Philadelphia on Thursday.

He's also wanted for a 2017 murder in his native Brazil, the district attorney's office said.

He was first seen with a beard and wearing a white T-shirt, gray shorts and white sneakers, but has since shaved his face and changed dark-billed baseball cap and green hooded sweatshirt in photos released by authorities.

Has Danelo Cavalcante been found?

Cavalcante has been sighted multiple times since his escape, most recently traveling outside of the police search perimeter to the home of an acquaintance he'd known several years ago. He unsuccessfully attempted to speak to the person through his doorbell security system, which captured the fugitive's new clean-shaven face, authorities said.

He stole a 2020 Ford Transit van, which was recovered abandoned and empty of gas in a field behind a barn in West Nantmeal Township, a rural area in northern Chester County.

Law enforcement released images Sept. 5 of a sighting of Cavalcante after security at Longwood Gardens received trail camera footage on their property, later confirmed to be Cavalcante. Longwood Gardens is a botanical garden in Kennett Square, Pennsylvania, about 40 miles west of Philadelphia and 11 miles south of West Chester, where Cavalcante escaped.

Officials are urging people near the area to check surveillance cameras around the home, cars and to remain vigilant, and to call 911 immediately with any information on Cavalcante's current location.
