Police: This may be the first double-homicide investigation in county's recent history

There are no suspects in custody

(CNN) —  

Investigators have identified a suspect in the deaths of two teens who went missing during a hike, Indiana State Police said Sunday.

Autopsy results confirmed the victims as Liberty “Libby” German, 14, and Abigail “Abby” Williams, 13.

The bodies were discovered by search volunteers Tuesday along a railroad bridge near Dear Creek in Delphi, about 70 miles northwest of Indianapolis, the Carroll County Sheriff’s Office said in a statement.

Relatives dropped off the teens at Delphi Historic Trail on Monday afternoon. When they did not return to be picked up, family members called police.

Missing since Monday

This is believed to be the first double-homicide investigation in Carroll County’s recent history, State Trooper Sgt. Kim Riley said at a news conference.

Police are not releasing the cause and manner of death of the teens at this time.

The investigation

Police provided a photograph of a man who was on the Delphi Historic Trails about the time Abigail and Liberty were walking. They are asking help from the public to identify him so he can be contacted regarding what he might have seen.

Investigators are proceeding with caution and not calling the individual in the photograph a suspect. There is no suspect(s) in custody at this time, police said.

“There is someone out there that did this crime and we’re going to track them down,” Sheriff Tobe Leazenby told CNN affiliate WXIN. “Folks should continue with business as usual but be more mindful and watch your surroundings a little closer.”

Police are asking anyone who has information on the case to call the Carroll County Sheriff’s Office at 765-564-2413, the Delphi Police Department at 765-564-2345 or Indiana State Police at 765-567-2125.

Police said callers may remain anonymous.
