DELPHI, Ind. – Indiana State Police say there will be a “new direction” in the investigation of the February 2017 homicides of Abigail Williams and Liberty German, Delphi eighth-graders killed while hiking on community trails during a day off school.

At noon Monday in Delphi — in an emotionally charged press conference in which ISP Supt. Douglas Carter at one point said the suspect could be in the very room he and media had gathered — officials released new video and an updated sketch of the murder suspect.

Carter said authorities believe the suspect to be between 18 and 40-years-old and potentially lived or currently lives in or works in Delphi.

"We believe you are hiding in plain sight," Carter said. "Maybe in this room."

Authorities also released additional video from Libby's phone of the suspect on the Monon High bridge. The new releases were extended versions of previously released audio and video.

Carter said Monday that families of both girls have agreed to a two week period of no media interviews. The families were informed of the new information and direction Monday morning.

Carter also said police are now looking for the driver of a vehicle that had been parked at the DCS office in Delphi, later found between noon and 5 p.m. on Carroll County Road 300 North, near the Hoosier Heartland Highway.

ABOUT THE CASE

► WHAT HAPPENED: Abby and Libby were hiking on the Monon High Bridge trail, a popular trail near Delphi, on Feb. 13, 2017. When they didn’t arrive to meet their ride at the trailhead that afternoon, police and community volunteers searched the trail and the surrounding woods. The girls were found on Feb. 14, about a half-mile up Deer Creek from the abandoned Monon High Bridge rail trestle.

► THE INVESTIGATION: Hundreds of investigators, including those from the FBI, were stationed in Delphi in the initial months of an investigation that brought in tens of thousands of tips. No one has been arrested in the case. At the second anniversary of the homicides, police said it wasn’t a cold case and that investigators were still assigned to the case.

► THE SUSPECT: Police continue to look for a white male between 5-foot-6 and 5-foot-10, weighing 180 to 200 pounds, with reddish brown hair. The description was taken from images on Libby German’s cellphone of a man walking across Monon High Bridge that day – wearing blue jeans, a blue jacket and a hat – and from composite done by an FBI sketch artist, based on information from a witness who saw a man fitting that description. Police also release a recording, taken from Libby’s phone, of a man saying, “Down the hill.”
