This is from my hometown, I was in the 11th grade, about 1/4 mile from my house.

Federal and local authorities are using a previously unreleased tip and new photos in asking the the public's help to solve 24-year-old missing persons case

Mark Himebaugh was last seen in 1991 leaving his family's home in Middle Township to watch firefighters battle a marsh blaze. A single shoe found on Delaware Bay beach was the only trace of the then 11-year-old after hundreds of volunteers combed the the area.

Authorities issued a photograph showing what the now 35-year-old man might look like and publicly released a 2010 phone call by a man who described himself as "the son of the witness of the crime" made from a pay phone in the Port Richmond area of Philadelphia.

The caller, in the edited call to the National Center for Missing and Exploited Children, said "Gilbert Patrick Marie" was involved in the boy's disappearance, the report says.

Investigators have come up empty locating a person by that name but are asking for the public's help to identify the voice. Fliers were also handed out fliers in the Philadelphia neighborhood.

Himebaugh's mother, Maureen, has kept the same phone number for the last 24 years hoping her now adult soon will call. Himebaugh's 35th birthday passed at the end of last month.

She told, "this is going to be our year."

The release of the recording came just days after the Cape May County Prosecutor's Office and Middle Township police held a press conference on June 1 to announce new efforts in the case.

Local investigators have set up a command post and will be conducting another round of interviews along with FBI and National Center for Missing and Exploited Children officials, the Cape May County Herald reports.

Authorities also called for the public's help on social media.

In 2012, an anonymous donor offered $25,000 for the safe return of Himebaugh and $10,000 for credible information about his disappearance.

Anyone with information can contact Middle Township police at 609-465-8700 or the national missing child hotline at 1-800-THE-LOST.
