Long Island serial killer case: after 11 years, could answers be coming?

Authorities may release a decade-old 911 call with new police commissioner poised to prioritize case

Shannan Gilbert's grave in Amityville cemetery lies eight miles from where she went missing in May 2011 after visiting a client at Oak Beach, a spit of sand dotted with holiday homes on New York's Long Island, three miles short of Gilgo Beach, where her remains were found eight months later.

Gilbert's final resting place, with a simple headstone at the back of the cemetery inscribed with her dates - 24 October 1986 - 13 December 2011 - speaks to an enduring mystery of how she, along with 10 or more other women, mostly sex workers who advertised on Craigslist, ended up dead along the same stretch of scrubby barrier marshes more than a decade ago.
