The FBI says tips related to a fugitive from Scottsdale on the 'Top Ten Most Wanted' list have increased since CNN aired a special program on Sunday.
Robert Fisher's wife and two children were found dead inside their Scottsdale home on April 10, 2001. The home had also been set on fire.
Fisher has been on the run since then -- police found his car and his family dog near Payson, but found no traces of Fisher himself.
The FBI still hopes he will be found, and they don't have reason to believe he is dead.
Since CNN's coverage on Sunday, the FBI has received more than a dozen tips, even some from other states and countries.
In April, the FBI released new photos of what Fisher would look like at his current age, 55. He hasn't been seen in a known photograph since 1999.
