In March 2014, Casquejo climbed to the top of the topped-out, but not yet completed, 1,776-foot (541 m) One World Trade Center.[3] Casquejo, then 16 years old, entered the site through a hole in a fence. He was subsequently arrested on trespassing charges.[4] He allegedly dressed like a construction worker, sneaked in, and convinced an elevator operator to lift him to the tower's 88th floor, according to news sources. He then used stairways to get to the 104th floor, walked past a sleeping security guard, and climbed up a ladder to get to the antenna, where he took pictures for two hours.[5] The elevator operator was reassigned, and the guard was fired.[6][7] It was then revealed that officials had failed to install security cameras in the tower, which facilitated Casquejo's entry to the site.[8][9]
In July 2014, in a plea agreement, Casquejo admitted to breaking a city misdemeanor law against scaling tall buildings without permission. He was sentenced to 23 days of service (which he completed with an extra six days). He submitted, as was required, a 1,200-word essay explaining what he had learned from the episode.[10]
Weehawken Water Tower
In September 2014, Casquejo was again arrested for scaling the 175-foot (53 m) Weehawken Water Tower. He was charged with defiant trespassing and resisting arrest.[11][12]
70 Pine Street
On February 21, 2016, Casquejo was charged with misdemeanor BASE jumping and trespassing for climbing above the roof at 70 Pine Street, an 850-foot (260 m), 67-story luxury apartment in the Financial District.[13] He avoided jail time in the sentencing on September 6, 2017, after pleading guilty to BASE jumping. He was granted youthful offender status; the case will eventually be sealed.[14]
Paramount Tower
In June 2017, Casquejo was arrested at the 568-foot (173 m)[15] Paramount, a 52-story residential skyscraper on East 39th Street in Turtle Bay, Manhattan.[16][17][18] In September 2017 Casquejo pleaded guilty to second-degree trespass in exchange for three years' probation for scaling the luxury apartment building.
Despite his probation, Casquejo has made other climbs,[25] for which he was arrested.[26][27][28][29][30] As of January 2024, he regularly shares Instagram reels featuring himself engaging in similar feats of climbing tall structures, primarily in New York City, but also in Hong Kong.[31][32]
