The death toll from superstorm Sandy is up to 75 in the United States and expected to keep climbing as workers comb through floodwaters, rubble and fallen trees in the more than a dozen states affected by the 900-mile-wide weather system.

As the cleanup began, stories of tragedy and heroism emerged. An 8-year-old Pennsylvania boy was crushed by a falling tree when he went out to check on the family's newborn calves. A New York police officer saved seven members of his family before drowning in raging floodwaters invading the family's basement. A Brooklyn couple died together when a tree fell on them as they walked their dog - which survived.

“We will get through the days ahead by doing what we always do in tough times — by standing together, shoulder to shoulder, ready to help a neighbor, comfort a stranger and get the city we love back on its feet,” New York Mayor Michael Bloomberg said.

Perhaps no story captured the drama and tragedy of Sandy better than that of NYPD police officer Artur Kasprzak. The 28-year-old drowned Monday night after rescuing seven members of his family, including his 15-month-old son, from the flood waters filling the basement of his Staten Island home. After getting them to safety by ushering them into the attic, Kasprzak went to the basement one more time but never returned, according to an NYPD news release.

Police responded to his family's desperate 911 call, but scuba divers who arrived in inflatable Zodiac boats and jet skis couldn't reach the home because of downed power lines snaking through the water.

“He was really a great guy, well-liked, very professional and hard working," Kasprzak's commanding officer, Deputy Inspector Edward Winski, told the Daily News. "It was very difficult this morning when I had to tell everyone. It's heart-breaking, to be honest with you."

Claudine Christian, 42, was knocked off the replica ship, which had been featured in several movies, and was found in the turbulent waters of the Atlantic four hours later. Search crews are still hunting for the ship’s captain, Robin Walbridge, who is believed to be wearing a survival suit that can keep him afloat.
