 A search party comprised of local police, sheriff's deputies, firefighters and DNR officers was formed to canvass the area where the girls were last seen. Hundreds of people, including police, firefighters, family, friends and residents of the surrounding community, searched for the girls into the night Monday and again Tuesday morning. They noted the bodies were found about 12:15 p.m. about a half to three-quarters of a mile upstream from Monon High Bridge, which is part of the Delphi Historic Trails. “There is nobody of interest at this point in time that we can say.”

 The girls were supposed to meet at the bridge to be picked up later in the day, but never showed up. The Delphi Fire Department also assisted in the search, and their headquarters was used as a makeshift command center. It was very somber.” 
 
 An Amber Alert was not issued because police said the case did not meet the criteria, which includes knowledge that a child under the age of 18 is in imminent danger and details about a vehicle or person possibly involved in the incident. “Even if we would have put an Amber Alert out, it wouldn’t have done this case any good,” Riley said at a press conference. “The short period of time and the location where the bodies were found, it would not have helped us in finding them.” 
 
 Police initially said there was no foul play suspected, but that changed a day later. On Tuesday, police announced they found two bodies in Delphi, along Deer Creek, about a half mile from the railroad bridge where the girls had last been seen. “It’s played tremendously on the emotions of this community.” 
 
 Indiana State Police Sergeant Kim Riley told reporters, “One thing the family asked us to do is to thank the communities around Delphi and the people here in Delphi for assisting in attempting to locate the two young children who were missing here earlier. Kim Riley said at a news conference shortly after 2 p.m. Tuesday. — Police didn't identify whose bodies were found Tuesday near Deer Creek, but indications were that they were 13-year-olds Liberty German and Abigail Williams, who had been missing since 5:30 p.m. Monday. The girls were last seen in a photo posted to German's Snapchat account showing Williams walking along the bridge. Authorities at Tuesday's press conference were not at liberty to say much about the investigation. Sergeant Kim Riley with the Indiana State Police wouldn't go so far as to identify the bodies as the girls in a press conference Tuesday, but they do suspect foul play. "I think people in the community are smart enough in our community to draw their own conclusions about what they should feel and shouldn't feel," Delphi Police Chief Steve Mullins said. “Our people are very smart. They are a very good community and they are very strong. And they are able to draw their own conclusions about this whole situation I think quite successfully.” 
 
 The reporter clarified that he asked the question because some may be concerned when they hear the words “foul play suspected” that there may be somebody “preying on people that they need to be afraid of.” 
 
 Mullin said he “understands” what he is saying, and again responded, “I think people are able to draw their own conclusions about this situation, and they’re smart enough to figure out what this situation warrants them to think. The Delphi Community Schools Corporation sent home a letter with students on Tuesday that said the bodies found were two of their missing middle school students. “It is with heavy hearts that the school corporation day comes to an end. It is our understanding that the two bodies found today were those of our two missing Delphi Community Middle School students,” the school district said in a statement to WRTV. The letter also said that counselors and local pastors will be available to all students and staff while they deal with the tragic situation. “I know it’s had a terrible effect on our people and we are grieved this sort of thing would happen here in our community,” Chief Mullins said. “There is someone out there that did this crime and we’re going to track them down,” Carroll County Sheriff Tobe Leazenby told reporters. “I think people need to be cautious and careful,” Riley said.
– Two 13-year-old Indiana girls had Monday off from school and were dropped off at a popular hiking spot in Delphi, but didn't show up when it was time for them to be picked up—and on Tuesday, their bodies were found. On Wednesday, police officially identified the bodies as Liberty German and Abigail Williams, the AP reports. Police say that foul play is suspected, the Indianapolis Star reports; their deaths are being investigated as homicides. The girls were dropped off around 1pm Monday and were supposed to be picked up later by family members, who searched the area when the girls didn't meet them as planned. They were reported missing at 5:30pm, and search parties set out; the bodies were found around 12:15pm the next day near Deer Creek, a half-mile or so upstream from Monon High Bridge, an abandoned railroad truss that spans the creek, where the girls had been dropped off. The bridge is a popular hiking spot—"a lot of people go out there for a little hiking, a nice day in the woods, get a little exercise," a local tells the Lafayette Journal & Courier—and Heavy notes that, even before her daughter went missing, Abigail's mother had a picture of it as her Facebook cover photo. The last known photo of the girls is a picture of Abigail walking along the bridge, which has no guard rails, that Liberty posted to her Snapchat account around 2:07pm Monday, the Indy Channel reports. Per the Logansport Pharos-Tribune, police say they suspect foul play "because of the nature of the bodies." The public information officer for the Indiana State Police says autopsies will be done Wednesday; authorities have not commented publicly on cause of death. The school district sent letters home with students Tuesday saying that counseling will be available.
