Authorities say there has been a surge in tips in the investigation into the slayings of two northern Indiana girls since the release of a sketch of a man suspected in the February killings. Investigators received at least 1,000 leads via email and telephone within 24 hours of Monday’s release of the FBI artist’s sketch of the main suspect in the murders of 14-year-old Libby German and 13-year-old Abby Williams.
