A suspect is in custody in connection with the murders of 13-year-old Abigail Williams and 14-year-old Liberty Herman, who disappeared while walking the popular trail in Delphi, Indiana, in 2017, multiple sources told the CBS affiliate in Indianapolis WTTV. The man was taken into custody on Friday, the station reported.

CBS News did not immediately confirm the suspect’s name. Indiana State Police announced that they will hold a press conference on the case Monday morning in Delphi.

The girls went missing on February 13, 2017, and their bodies were found a day later in a wooded area near the historic Delphi Trail, about a mile from where they were last seen. Their deaths have been ruled a homicide.

Days after the disappearance, investigators posted a photo with the suspect it was a white man wearing blue jeans, a blue jacket and hoodie, and an audio recording. In April 2019, a video clip recorded on German’s mobile phone with an updated sketch was released.

Over the years, investigators viewed thousands of potential customers were looking for the man, but no arrest warrants were issued and no arrests were made.

Herman’s sister, Kelsey, tweeted early Friday: “Just know how thankful I am for all of you… Today is the day.”

Last year, Herman’s grandmother remained confident that he would be arrested.

“Today or tomorrow, [the clock] “I wonder,” said Becky Petty. “Technology is getting better and better, and we’re going to get it.”

Delphi is about 70 miles north of Indianapolis.
