The reward for information leading to the discovery of Kyron Horman has been increased to $50,000, but a Multnomah County Sheriff's Department press conference didn't reveal much new information.

Horman is the seven-year-old who went missing almost eight weeks ago.

Investigators said they called the press conference today to provide answers to written questions from the media about the case.

But they began by saying they would not discuss any criminal investigation or take any additional questions.  What they did say was that the search for Kyron Horman is now the largest search effort in Oregon's history.

Monte Reiser: "Never before has there been a combined search and rescue contingent of approximately 500 searchers involving 18 different counties and several other agencies from other states."

Captain Monte Reiser of Multnomah County Sheriff's office said they've dedicated 11-thousand hours to the investigation and received 35-hundred leads from thousands of tips.

Monte Reiser: "Typically, tips are called in and are filtered, prioritized and triaged by an experienced detective allowing for effective dissemination of information to the appropriate resource.  All tips are recorded and tracked using software specifically designed for this purpose. Once a tip turns into a lead, it is assigned to a detective or multiple detectives and is worked and continues to be tracked using the software."

He said some tips, such as those from psychics, produce no workable leads, but they will be kept and worked on later if necessary.

Answering other written questions, he said polygraphs are simply an investigative tool that may help to further an investigation.  He said the East Multnomah County Major Crimes team has a 90% success rate.

And also addressed concerns that other missing children aren't getting the same attention as Kyron Horman.

Monte Reiser: "In response to an earlier question, at this time in Multnomah County or the Pacific Northwest region, we are not aware of any missing children cases that are like this one. Without hesitation, we can say that any case involving similar circumstances will be given the same attention that this one has."

Desiree Young, mother of Kyron Horman

After he finished, Kyron's mother, Desiree Young, again asked people to come forward with information.

Desiree Young: "We love you Kyron. Never give up hope. We are all coming to get you to bring you home."

After Young finished, authorities left the room without taking additional questions.

A great deal of attention in this case has been focused on Horman's stepmother, Terri Horman. But the police say they have neither have a person of interest nor a suspect.
