The number of deaths from Hurricane Sandy in New York has risen to 41, Mayor Michael Bloomberg said Friday, warning that more victims might yet be found.

Two of the fatalities found Thursday were the brothers Brandon and Connor Moor, ages 2 and 4, respectively, who were torn from their mother's arms by a torrent of flood waters as they fled Monday night from their home on Staten Island.

Their father, an employee of the municipal water department, was at work when the tragedy struck.

Meanwhile, Bloomberg confirmed that the southern end of Manhattan and the borough of Brooklyn, which continues without electricity, will have the power back on before midnight Friday, which will cut by at least a half the 460,000 users still in a blackout.

Utility Con Edison said electricity for the entire city will be up and running by Nov. 10, though authorities believe it could be sooner.

The mayor, during his usual daily press conference in which he reviews the city's recovery efforts in the wake of Sandy, said that many companies have offered to donate products.

While expressing his gratitude for the offers, Bloomberg said that donations of goods were not needed, since the logistics of distributing them would be very complicated. "We need money," he said.

Work begins Saturday to secure the part of a crane 23 meters (75 feet) long that dangles more than 200 meters (655 feet) in the air beside a skyscraper under construction. EFE
