Tips Pour in After Recording Released in Teen Girls' Murder

Indiana police say they've received 1,900 more tips after releasing a recording of a voice saying "down the hill" on Wednesday, the Indy Star reports. Police believe the voice belongs to the man who killed two girls Feb. 13 while they were hiking on the Delphi Historic Trail on the last day of winter break. The audio recording comes from a phone belonging to one of the victims, 14-year-old Liberty German. A poor-quality photo believed to be of the suspect was released last week and also comes from Liberty's phone. The other victim is 13-year-old Abigail Williams. Fox59 reports police have received 3,900 tips in the case total. A reward for information leading to an arrest and conviction has been upped to $50,000. (More child murder stories.)
