A Tarrytown mother's grief has led to the re-establishment of the Westchester chapter of New Yorkers Against Gun Violence.

Dozens of concerned residents joined Yonkers Mayor Phil Amicone and Gisela Marin at the Warner Library Thursday evening. Marin's daughter, 19-year-old Jessica Santos, was killed in a drive-by shooting on Beech Street in Yonkers in August 2006. Determined to prevent other families from feeling her pain, Marin says she will lobby for stricter laws that will take illegal guns off the streets.

New Yorkers Against Gun Violence Executive Director Jackie Kuhls says gun violence, responsible for 1,000 New York deaths annually, is preventable when the community stands up for itself.
