The family of a New York City construction worker killed in a construction accident that may have been the result of labor law violations has hired a New York City lawyer after identifying his battered body on Saturday. “The family wants accountability, they want answers, and they want it done publicly,” said the family’s attorney. Juan Ruiz, a 69-year-old construction worker, died Thursday when the Columbia University-owned warehouse on 131st Street he was working on collapsed, and a wrongful death lawsuit is very likely to follow. Columbia is in the midst of building a $6.4 billion new campus in the Manhattanville neighborhood of New York City.
