KINGSTON, N.Y. (AP) — Jury deliberations have begun in the New York murder trial of the sister of a sex worker whose disappearance led to the discovery of 10 sets of human remains strewn along a Long Island beach.

An Ulster County jury deliberated briefly Wednesday in the second-degree murder trial of 28-year-old Sarra Gilbert. Prosecutors say she stabbed her 52-year-old mother, Mari, more than 200 times and bashed her head with a fire extinguisher inside the mother's Catskills home last July.

Deliberations are scheduled to resume Thursday morning.

Shannan Gilbert, Mari's daughter and Sarra's sister, vanished in May 2010 after fleeing a client on a Long Island beach.

The search for the missing woman led to the discovery of 10 sets of human remains on Gilgo Beach. Police believe the 10 were victims of a serial killer but Shannan Gilbert accidentally drowned.
