Residents of southeastern Pennsylvania remain on edge following the escape late last month of a convicted killer.

According to Fox News, illegal alien Danelo Cavalcante was convicted of murdering his ex-girlfriend in 2021 and is also wanted for murder in his native Brazil.

Cavalcante believed to be in Chester County

Cavalcante managed to make his way out of the Chester County Prison on August 31, sparking off an almost two-week-long manhunt.

Philadelphia's ABC 6 Action News reported on Monday that state authorities believe Cavalcante continues to remain within Chester County.

However, is also thought to have "slipped out of the original search area, changed his appearance, stole a dairy delivery van and tried to contact acquaintances."

The news station noted that footage of Cavalcante has been recovered from a doorbell video camera while the dairy truck has since been found.

Residents told to remain vigilant

The Pennsylvania State Police put out a tweet on Monday asking local residents "to remain on the lookout and ensure vehicles and homes remain locked."
