"It's important, especially for Diane's family and friends," Henry said. "Obviously this had been very hard for them."
Henry said the family does not wish to speak publicly at this time. She declined to comment on why Patterson revealed where Corado's remains could be found at this time.
Patterson - also charged with kidnapping - is scheduled for trial for early July.
Authorities allege he abducted Corado and a friend who was sleeping at her apartment in December 2010. Patterson reportedly beat Corado with a metal pipe, threatened her with a kitchen knife, and forced both women into Corado's car. He released the friend and took off with Corado still in the car.
Corado's 2004 Pontiac later was found parked in Camden, the interior stained with blood. Patterson was arrested after leaving a motel room in Maple Shade, his clothing also stained with blood.
Although Corado's body had not been found, authorities in Pennsylvania charged Patterson in 2011 with murder and related charges after Corado was presumed dead.
A former roommate of Patterson told authorities at the time that Patterson wanted to reunite with Corado, and threatened if she did not take him back that he would kill her, and dump her body in a remote area of South Jersey.
