Officials in Pennsylvania say they believe escaped murder convict Danelo Souza Cavalcante broke into a home in Pocopson Township.

Cavalcante escaped from the Chester County Prison on Thursday morning and the U.S. Marshals Service says he's also "wanted for a homicide in Brazil." Officials believe he's headed south.

Immigration officials said they aren't sure when exactly he entered the U.S., but told Fox News Digital that he was not "inspected or admitted by a U.S. immigration official."

During a Saturday afternoon press conference, Chester County District Attorney Deb Ryan said that officials believe Cavalcante broke into a home, but was stopped.

"There's a strong belief that it was Mr. Cavalcante who went into this home and was thwarted by a homeowner at the time. He matches the description, but we have not been able to confirm to the homeowner who saw him face to face at the counter," Ryan said, speaking to the break-in in the Pocopson Township home.

The alleged intruder was described as a "small man wearing a backpack," which Ryan says fits the description of Cavalcante.

Earlier on Saturday, the Chester County District Attorney's Office announced that the man was spotted in a residential area over the weekend.
