A 51-year-old Jefferson man was killed instantly Tuesday morning when a tree crashed into his house, police said.
The death was the fourth in Morris County linked to Tropical Storm Sandy.
The storm also led to the deaths of a man and woman in Mendham Township Monday night when a tree fell on their pickup truck. Two children inside the vehicle, an 11- and 14-year-old, survived.
Earlier Monday, Kinnelon police said an 84-year-old man died of a heart attack while he was outside preparing for the storm.
Many roads were impassable for most of Tuesday and 87 percent of the county lost power.
Gov. Chris Christie reported four other deaths around the state—.
Tropical Storm Sandy damaged the roof of Lake Hiawatha School in Parsippany and many other homes in the area were damaged by falling trees. The widespread damage and outages led many school districts to close schools Wednesday and postpone Halloween trick-or-treating.
Jersey Central Power & Light said the damage was the worst in its history and has told some towns it could take seven to 10 days to have power restored.
