The inmate who escaped from Chester County prison crab-walked his way out, stunning video shows

• A prisoner escaped Chester County Prison by using a 'crab walk' climbing technique, a warden said.
• A video shows Danelo Cavalcante crawling up two walls by placing his hands and feet against them.

Surveillance footage captured the moment a convicted killer used a "crab walk" climbing technique to escape from a Pennsylvania prison.

The video, shared by the local District Attorney's Office on Wednesday, shows Danelo Cavalcante "crab walking up" two walls separated by a 5-foot hallway on August 31, according to ABC News.

The 23-second clip shows the 34-year-old convicted inmate placing his hands on one wall and his feet on another wall to push his way upwards.

Howard Holland, the acting warden of the Chester County Prison, told ABC News that Cavalcante proceeded to run across the roof, dive through barbed wire, and scale more razor wire.

Cavalcante was reported missing when convicts were brought back in from the exercise yard at 9:35 a.m., Holland said, adding that the prison was placed on lockdown and a head count confirmed his disappearance, according to ABC News.

At 10:01 a.m., he said, a public escape siren was triggered.

An officer in the guard tower above the exercise yard, where the escape occurred, "did not observe nor report the escape," and is a "key part" of an ongoing internal inquiry, Holland said, per ABC News.

Another inmate, Igor Vidra Bolte, used the same method of escape and route to break out of the same county facility in May, according to a criminal complaint obtained by the outlet.

Bolte was caught within five minutes of getting out of the prison, the outlet reported, citing the complaint.

Cavalcante, however, is still on the run, Pennsylvania State Police said on Thursday, according to Philly Crime Update — eight days after his escape.

The acting warden said Cavalcante was at the jail awaiting transfer to the state prison.

The 34-year-old convict was sentenced to life in prison without parole on August 23 for fatally stabbing his 33-year-old ex-girlfriend, Deborah Brandão, outside her home in Schuylkill Township in April 2021, in front of her two young children, aged 4 and 7, the Chester County district attorney's office said in a Facebook post.

Chester County Detectives and the Pennsylvania State Police are conducting a thorough countywide search.

The Pennsylvania Crime Stoppers is offering a prize of $20,000 for information leading to Cavalcante's arrest, per Pennsylvania State Police.

Cavalcante was last spotted near Chandler Road in Pennsbury Township on Tuesday evening, Pennsylvania State Police said, per WPVI-TV.

He is also wanted for homicide in his native Brazil, the US Marshals Service said.
