Danelo Cavalcante, a convicted murderer who escaped from a Pennsylvania prison more than 10 days ago, was spotted again on Monday night, the authorities said.
James Mckee, a Pennsylvania State Police trooper, confirmed the sighting in a brief telephone interview on Monday night. He said he could not confirm any other details.
Mr. Cavalcante, 34, clambered up a wall and escaped from Chester County Prison on Aug. 31, days after he was convicted of murdering his ex-girlfriend in 2021.
Mr. Cavalcante has since eluded hundreds of law enforcement officers in quiet, wooded communities outside Philadelphia, stirring a relentless unease among residents.
He has been spotted several times, even as officers use drones, dogs and helicopters to find and arrest him. But as midnight neared on Monday night, he was still at large.
Mr. Cavalcante, a Brazilian national, is also wanted for a 2017 murder in his home country.
After more than a week of hiding out in the quiet communities south of the jail, he slipped through a perimeter set by law enforcement and stole a delivery van over the weekend. On Saturday night Mr. Cavalcante was seen on a doorbell camera miles away. Police are now searching an area deeper in the Pennsylvania countryside, where he abandoned the van, apparently after it ran out of gas.
On Monday, officials told reporters that Mr. Cavalcante’s recent movements had changed the nature of the search. They urged people in the area to be vigilant and warned of consequences for anyone who helped him.
