The young boy was at the park with his father, Miguel Ortega, and his five-year-old sister at the time of the incident.His parents, Miguel Ortega and Claudia García, have now launched legal action against several companies involved in the design, construction and installation of the monument.According to the lawsuit filed, the monument commemorating U.S. Navy Captain Albert H. Rooks and USS Houston The CA-30 was extremely heavy and inadequately supported.The structure “collapsed within seconds and crushed Caleb,” the lawsuit alleges.First responders transported the child to the hospital, but he later died from his injuries.The tragedy became even more devastating for the family because Caleb’s mother was working as a nurse at the same hospital when her son was brought in by ambulance.Garcia witnessed emergency efforts to save his son’s life. The lawsuit says the experience caused severe emotional trauma.The family is seeking compensation for wrongful death as well as emotional distress caused to Caleb’s parents and his sister, who witnessed the incident firsthand.Following the tragedy, a fundraising page was launched to support the family.“At the beginning of a normal, happy day filled with play and fun, an unimaginable accident occurred that took Caleb from us too soon,” the GoFundMe page reads.“No one could have predicted the heartbreak that would follow.”“Caleb was a happy, busy little boy who filled every moment with life.”“He was always on the move, happiest when he was playing, exploring, and especially when he was with his big sister, his best friend. The two of them spent hours together, laughing, playing and making memories that their family will always remember.”Page also recalled his love of monster trucks.“Caleb had a special love for monster trucks and was very proud of his collection. Each night before he went to sleep, he would carefully line them up, showing off his sweet and thoughtful little personality.”“His smile and those beautiful, bright eyes could light up a room, and he was deeply loved by all who knew him. He brought so much joy to his family and friends, and being with him was truly something special.”The lawsuit argues that park visitors should have been warned about the potential danger posed by the monument and alleges negligence in its design, construction or maintenance.Those named as defendants include Boulder Designs, Boulder Designs Franchising LLC, Border Magic, Builders FirstSource Inc., American Rock Products, Wenzel Nursery, Double T Construction Ltd., Neil Binder and Binder Matrimonial Communities.The US Army Corps of Engineers, which operates Rooks Park, temporarily closed the site and cordoned off the area for two weeks after the incident.
