Among those volunteers was the father of slain teen Amber Dubois.
“We’re making sure no predators can stalk their prey here,” Maurice Dubois said.
City Councilman Dick Daniels rounded up the volunteers to remove non-native brush and trim overgrown trees in the area, which is roughly 1 mile north of where Chelsea's body was discovered in a shallow grave near the shore of Lake Hodges.
Amber’s remains were found last weekend on the Pala Reservation east of Interstate 15.
John Albert Gardner III, who pleaded not guilty in the rape and slaying of 17-year-old Chelsea King, is also the focus of the investigation into Amber’s death.
Maurice Dubois said he was planning on attending Chelsea’s memorial service in Poway on Saturday to show his support to the King family.
“We are like family now. We’re extremely close,” he said.
Amber was last seen just after 7 a.m. Friday, Feb. 13, 2009 about a block from Escondido High. She was 14-years old at the time.
