HUDSON COUNTY — Hudson County Sheriff Frank Schillari is expected to announce on Feb. 7 that patrol shifts for county sheriff’s officers will be increased to go around the clock, 24 hours a day, 7 days a week. Although their duties generally involve protecting county courts and delivering warrants and other legal notices, the elimination of the county police in 1995 made patrolling county parks and county streets also one of the duties. Previously, these patrols were limited to specific hours, something Schillari is expected to change with the announcement.
