Two wrongful-death lawsuits filed late last month in the New York State Supreme Court in Manhattan allege that public safety officials with New York City, employees working for crane owner James F. Lomma, site contractors and consultants knew that a Kodiak tower crane was unfit for service before it collapsed and killed two workers last May. Attorneys for the families of the victims— crane operator Donald C. Leo and Ramadan Kurtaj, a sewer technician who was working near the crane—are suing the city and other parties seeking damages.
