Mangano: Snow helped nab suspect
Nassau County Executive Edward Mangano said crews began brining county roads at midnight. By noon Thursday all county roads had been plowed at least twice, some as many as four times, he said.
"Conditions are passable but I urge motorists to slow down and leave space between cars," he said.
Mangano said there have been 63 reported -- mostly fender benders -- which is higher than a normal day but less than recent snow storms.
The snow, however, has also served as a useful crime-fighting tool, he said.
A man who robbed a Dunkin' Donuts in Massapequa was apprehended by Nassau police after they followed his footprints to his home, Mangano said.
Thursday's storm, Mangano said, will drain the county's $1.4 million snow budget for 2014, which covers supplies such as sand and salt and overtime for Department of Public Works employees.
The county has a crew of 238 DPW employees working during todays storm.
Mangano said the county will now be forced to move funds from other areas of the DPW budget to cover the shortfall.
The county had 6,000 tons of salt on hand before the storm and expect to use about 2,000 tons today through Friday. The county will order more supplies as early as next week.
"We have an adequate supply of salt and sand right now," he said. -- ROBERT BRODSKY
