ALBUQUERQUE, N.M. (AP) — Officials in Albuquerque have unveiled plans for a memorial park that will honor the 11 women whose bodies were found in a mass grave and are believed to be victims of a serial killer.

The Albuquerque Parks and Recreation Department and City Councilor Klarissa Pena on Thursday released the final design after years of work to secure land and funding.

Officials say the design was approved by family members of the victims. The families helped select trees, shrubbery, benches and other design features.

In 2009, the discovery of a human bone by a woman walking her dog led police to the mass grave on Albuquerque's west side.

Authorities say many of the victims worked as prostitutes or were involved in drugs before they disappeared between 2003 and early 2005.

The case has never been solved.
