Thousands of tips have poured in over the years, most in the weeks and months after Amber vanished. A handful are still phoned in every month. Despite all this, officials say they are no closer to solving Amber's case.
"It's been extremely frustrating for it to go on this long and not have it solved," said Detective Lopez. "We have other cold cases and they're all frustrating, we want to solve them all, but 20 years is a long time. It's frustrating not to be able to give the mom and the family an answer."
Amber's younger brother, Ricky Hagerman, who was riding his bike alongside Amber that day, joined in the plea for answers at the press conference.
"I didn't quite understand what was going on," Ricky Hagerman, now 25, said at the Tuesday press conference. "We want closure and we want justice, so if you have any information, please come forward."
