PhHOENIXVILLE: A convicted murderer who escaped from a Pennsylvania prison over a week ago has changed his appearance to elude capture including shaving his beard and moustache, photos released by police showed today after a new sighting of the man.

The images showed Danelo Cavalcante, 34, clean-shaven and wearing a hooded sweatshirt, black baseball cap, green prison pants, and white shoes, police said. The photos appeared to be taken from security cameras on the front porch of a house.

Police said Cavalcante was seen near the town of Phoenixville, about 48km northwest of Philadelphia, yesterday night.

He escaped on Aug 31 from Chester County Prison in the same region where he was awaiting transfer to a state prison to serve a life sentence for killing his ex-girlfriend.

Pennsylvania State Police said he was driving a 2020 white Ford Transit van with a refrigeration unit on the top, and asked the public to contact law enforcement if seen.

Cavalcante, a Brazilian national, is also a suspect in a 2017 murder in Brazil, the US Marshals said.

There have been multiple sightings of Cavalcante since his jailbreak. Last week, school districts in the area cancelled classes for a day after one such sighting, officials said.

Police have offered up to US$20,000 for tips leading to his capture.
