He appeared to check around for any spectators before putting his hands on the walls to his right and his feet on the walls to his left and propelling himself vertically up the walls to escape.
Holland also noted that that was how another inmate, Igor Bolte, also made his escape from prison on May 19, according to NBC News. After Bolte was captured about a half-mile from the prison in a residential neighborhood, Holland said razor wire was added to the roof to prevent a similar escape, per the outlets. However, he said Cavalcante was able to push through the razor wire to get out.

Holland also said there may have been a human error factor in his escape, as a correctional officer watching the area on the watchtower did not see Cavalcante on the roof. He said officers may not have caught the escape taking place due to a basketball game taking place in the yard at the time, per CBS News.
“With the time it took him to go up, and we all saw the video, it wasn’t very long," Holland said, per NBC News. “It’s feasible that we didn’t see it because we just weren’t focused on it.”
