AMITYVILLE, N.Y. (CBSNewYork) – A funeral will be held Thursday for a Jersey City woman whose disappearance led to a serial killer’s dumping ground on Long Island. Shannan Gilbert , a 24-year-old escort, disappeared on May 1, 2010. Her remains were found in a marsh on Oak Beach in December 2011. Investigators then found the remains of 10 other women along Ocean Parkway. They suspect a serial killer is responsible, but don’t believe Gilbert’s death is linked to the others. Gilbert will be buried in Amityville Cemetery.
