Illegal alien convicted for fatally stabbing woman 38 times in front of her kids escaped Pennsylvania prison by walking backward and up a wall

 A convicted murderer walked out of Chester County Prison in Pennsylvania on Aug. 31, prompting a manhunt that has yet to be resolved. The most striking thing about Danelo Cavalcante's escape was not that the Brazilian national managed to walk out prison, but the fact that he did so backward and up a wall. 

Security camera footage of the illegal alien's escape released by authorities Wednesday shows how the 34-year-old pulled it off. 

Around 8:51 a.m. last Thursday, Cavalcante stole into an egress off one of the prison's exercise yards, where KYW-TV indicated another inmate, Igor Bolte, had made his way out earlier this year, only to be caught five minutes later. Rather than futilely pound at the sealed door, the five-foot-tall murderer pressed his hands against one wall and his feet against the opposite side. He then slowly walked backwards, skyward and out of view of the cameras.

The New York Times reported that after acrobatic stunt, Cavalcante pushed through the razor wire that had been installed after the previous escape attempt, then made his way onto the roof. Atop the roof, where he apparently went unseen by the officer manning the lookout tower, who is now on administrative leave, he scaled a fence, pressed his way through more razor wire, then put significant distance between himself and the prison. 

His absence was not discovered until the regularly scheduled inmate count, prompting a prison lockdown around 9:50 a.m. and the sounding of public sirens ten minutes later.

Security cameras along the trail of Longwood Gardens, which spans 1,077 acres in Kennett Square, Pennsylvania, caught the fugitive on film Monday night.

Authorities focused their search in Pocopson Township on Tuesday, stressing to residents the need to lock their doors and stay inside, noting that Cavalcante is extremely dangerous.

Chester County District Attorney Deb Ryan said, "Lock your doors, keep your eyes on your kids, and keep your eyes on your neighbors and your friends."

Although state police, the FBI, and U.S. Customs and Border Protection are presently aiding in the search, local officials are taking no chances, shuttering the Kennett Consolidated and the Unionville-Chadds Ford school districts, reported WHYY-TV.

Thursday afternoon, officials noted that the killer is "believed to be in the perimeter of Routes 926 and 52, Hillendale Road and Creek Road."

Pennsylvania Crime Stoppers and police are offering a combined $20,000 reward for information leading to the Brazilian's arrest.

Ryan's office indicated the Brazilian was convicted of first-degree murder for grabbing his 33-year-old ex-girlfriend Deborah Brandao by the hair and throwing her to the ground outside her home in front of her 7-year-old and 4-year-old children, then stabbing her 38 times "in virtually every vital organ including her heart, kidney, lungs, and liver."

After the stabbing, the victim's 7-year-old daughter told police the Brazilian murderer had showed up to their house and said "he was going to do something bad to their lives and pulled two knives out from a black bag that was behind his back," reported CNN.

When the little girl began to scream, Cavalcante smashed her with a rock.
