The family of Amber Harris is receiving national support. Missing children's advocate Marc Klaas visited the Harris family Wednesday as plans firm up for Amber's memorial service.

Klaas plans to attend the memorial on Thursday.

Melissa Harris shares a common bond with Marc Klaas.

He says, "We both lost a child, 12-years-old, to predators. There's a pretty tight bond there. In both incidents law enforcement said our children ran away."

The 1993 murder of Polly Klaas made national headlines. Marc Klaas then went on to form the Klass Kids Foundation advocating for young victims like Amber Harris.

A few months ago the group organized a search for the then missing Amber.

Klaas says, "When you have a critical situation like Amber, most law enforcement don't know how to respond. They should know how to respond, have protocol, but they don't."

The police department says it did respond appropriately, followed procedure and took amber's case seriously but Klaas says it could have done more.

He says, "When you have a 12-year-old who disappeared without her belongings on a cold afternoon in the end of November, it's probably irresponsible to classify her as a runaway."

Klaas says Amber's death can be a catalyst to prevent future tragedy.

"It's also an opportunity for parents to respond talk to their kids about amber to give them tools to avoid victimization and empower them," he says.

Amber's family has moved the original location of the memorial service. It will take place at 10 a.m. Thursday, May 25, at Grace Apostolic Church at 2216 Military Avenue.

The public is invited to attend the service. It will be broadcast live on Channel 6 and we'll stream the service live here on WOWT.COM.
