TALLAHASSEE, Fla. (AP) - Billboards featuring 25 missing children, some now adults if still alive, are part of an annual commemoration at Florida's Capitol.

Gov. Charlie Crist and Attorney General Bill McCollum joined law enforcement officials and family members at the Florida Missing Children's Day ceremony Monday in Tallahassee.

The Florida Outdoor Advertising Association donated digital billboard space over the weekend depicting missing children dating to 1974 when Teresa Alfonso vanished from Marathon.

The most recent is Preston Mills who has been missing since June 25 in Pensacola.

Authorities are hoping people will recognize the pictures and provide information to reunite them with their families.
