With tips drying up, the Maricopa County Sheriff's Office is asking for the public's help in solving the case of two Phoenix teens found dead in the forest. Sheriff Jerry Sheridan says detectives have no suspects and no solid leads into the deaths of 18-year-old Pandora Kjolsrud and 17-year-old Evan Clark. Despite the long hours, investigators say they've reached a dead end and the killer or killers are still out there. Casey Torres reports.
