The Day the Girls Went Missing
Liberty "Libby" German and Abigail "Abby" Williams were dropped off to go hiking near Monon High Bridge just east of Delphi, according to family.
Libby posted a photo on her Snapchat account showing Abby walking across the old railroad bridge.
This was the last time anyone heard from the girls.
Between 2:30 p.m. and 5:30 p.m.
The girls had a set time to meet with family members to be picked up .
When family showed up to get them they were nowhere to be found. Family began canvasing the area for Libby and Abby but could not locate them.
After family could not locate the girls they contacted the Carroll County Sheriff's Department.
The Carroll County Sheriff's Department, Delphi Police Department, and Delphi Fire Department were joined by the Department of Natural Resources to search for the two missing girls.
Sheriff Tobe Leazenby said crews began canvassing the area and tried pinging the girls' cell phones into the evening hours but had no success in finding them. The sheriff said they believed the girls' phones were either dead or turned off.
The search was called off just before midnight. Family members continued to scour the area searching for Libby & Abby.
At this point in time, Sheriff Laezenby said they had no reason to believe that the girls were in imminent danger and crews would resume their search in the morning.
