Escondido police said the remains of Amber Dubois, the 14-year-old who disappeared last year on her way to school in California, have been found.
The discovery of Amber's remains came less than a week after the February 28 arrest of John Albert Gardner III.
Police suspect Gardner in the murder of Chelsea King, 17, who vanished on February 25 from a park about 10 miles south of where Amber disappeared.
"I certainly had hoped that when the day came to do a press conference on Amber, it would be under much different circumstances, but that was not to be," Escondido Police Chief Jim Maher told reporters on Sunday.
At the press conference, Amber's parents, Maurice Dubois and Carrie McGonigle, thanked the people who had helped search for her, especially the volunteers.
"They were the most dedicated people you could ever imagine," her father said. "Without them, we couldn't have done anything."
Amber was last seen around 7:00 a.m. on February 13, 2009, walking to Escondido High School. Despite intensive investigation and searches by local police and FBI investigators, she was never found.
Friends and family remembered the teen's deep love for animals. On the day she disappeared, she was carrying a $200 check to purchase a lamb for a project with Future Farmers of America. She also had a horse stabled near her home and had planned on participating in the animal husbandry program at Escondido.
Following Gardner's arrest, Amber's father voiced his suspicions that the same man was behind both abductions.
"They're both beautiful girls. There are so many similarities it's scary," he said.
Gardner, who served five years of a six-year sentence for molesting a 13-year old, was paroled in September 2008.
On Wednesday, he pleaded not guilty to charges of allegedly raping and murdering Chelsea and an attempted rape of another female in December.
Chief Maher would not answer questions about a possible connection between the two cases, saying the recovery of Amber's remains was part of an ongoing police investigation.
