A worker in his 50s died after being hit in the head by a tape measure that fell 50 stories from a construction site in Jersey City Monday, authorities say. The man, identified in a police report as Gary Anderson, of Summerdale, delivered Sheetrock to a 50-story apartment building under construction on Christopher Columbus Drive near Marin Boulevard shortly before 9 a.m. He parked his truck near the Christopher Columbus Drive entrance, got out and stopped to speak to someone on his way to the building.
