DELPHI, Ind. –- Indiana State Police posts have added more resources to assist in the investigation of two teen girls murdered in Delphi over a month ago.
Each ISP post has an investigation squad and troopers have been assigned to follow up on tips in their assigned post areas.
The Indianapolis squad has been assigned 140 tips in the past two weeks and troopers are actively checking on every single one.
Liberty German, 14, and Abigail Williams, 13, went missing after they were dropped off near the Monon High Bridge on Feb. 13. Their bodies were found the next day on private property less than a mile from the last place they were seen alive.
Investigators continue to look through the more than 13,000 tips given to police in hopes of finding the suspect who murdered the two teens.
We have had over 13,000 tips as of today. Keep the tips coming. #delphigirls

The case’s main suspect is a man found walking in the area during the time the pair went missing. His photo was found on German’s cell phone along with a clip of a man's voice saying "down the hill."
You can listen to that clip below.
A reward was set up by authorities for those who give information that lead to the arrest of the suspect. The reward is over $230,000.
The total sum of the reward is up to $231,235.00 and growing. #delphigirls
